Although, a part of your question is missing, you might be referring to this full question "How does crushing a candy to smaller pieces affect its digestion?"

Crushing the candy into smaller pieces increases the surface area of the solvent which will result in the reduction of digestion or dissolution.

Digestion is the process in which food taken is broken down into smaller components that can be absorbed into the bloodstream. Digestion helps in converting food into molecules, like glucose so that the body can utilize that energy for its growth and development.

While Crushing the candy into smaller pieces, we are increasing the surface area of the solvent which will result in the reduction of digestion or dissolution of the candy. Thus, the larger the size of the pieces, the slower will be the process of digestion. This physical process in which large pieces of food are cut and crushed into smaller pieces is known as mechanical digestion.

If 100.0 moles of H₂ and 40.0 moles of O₂, react to produce water, H₂ one is the limiting reactant.

When a chemical reaction is complete, the limiting reagent—also known as the limiting reactant or limiting agent—is the reactant that has been completely consumed. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained. Excess reagents or excess reactants are any reagents that are present in amounts greater than those necessary to cause a reaction with the limiting reagent.

Since the amount of product produced when the limiting reagent interacts entirely is defined as the theoretical yield, the limiting reagent must be identified in order to calculate the percentage yield of a reaction.

The limiting reactant is H₂ because it is the reactant that controls the amount of product produced. When 100 moles of H₂ and 40 moles of O₂ react, all of the H₂ will have been consumed, but there will still be O₂ left over. This means that the reaction was limited by the H₂ and that is the limiting reactant. The solution can be determined by using the following equation:

n(H₂) = 100.0 moles

n(O₂) = 40.0 moles

n(H₂) / (n(O₂) / 2) = ratio of H₂ to O₂

100.0 moles / (40.0 moles / 2) = 5.0

Since the ratio of H₂ to O₂ is 5.0, this indicates that there is more H₂ than O₂ and therefore H₂ is the limiting reactant in the reaction.

2 moles of [tex]O_{2}[/tex] gas and 1 mole of [tex]NO_{2}[/tex] gas would be produced from 2 moles of [tex]HNO_{3}[/tex] during electrolysis.

What is an electrolysis?

Electrolysis of nitric acid using graphite electrodes would result in the following reactions at the anode and cathode:

At the anode (oxidation):

[tex]2HNO_{3}[/tex] + 4 e- → [tex]O_{2}[/tex] + [tex]2NO_{2}[/tex] + [tex]2H_{2}O[/tex]

At the cathode (reduction):

[tex]2H^{+}[/tex] + 2 e- → [tex]H_{2}[/tex](g)

Overall reaction:

[tex]2HNO_{3}[/tex] (aq) +[tex]2H^{+}[/tex](aq) + 4 e- →  [tex]O_{2}[/tex](g) + [tex]2NO_{2}[/tex](g) + [tex]2H_{2}O[/tex](l)

This means that for every 2 moles of nitric acid, 1 mole of [tex]O_{2}[/tex] gas is produced. The products of the electrolysis are  [tex]O_{2}[/tex] gas, [tex]NO_{2}[/tex] gas, and [tex]H_{2}O[/tex].

The concentration of the nitric acid (4 mol/L) indicates that there are 4 moles of [tex]HNO_{3}[/tex] in 1 liter of solution. To calculate the number of moles of  [tex]HNO_{3}[/tex] in a given volume of solution, we can use the following formula:

moles of solute = concentration × volume (in liters)

For example, if we have 500 mL (0.5 L) of the 4 mol/L nitric acid solution, the number of moles of [tex]HNO_{3}[/tex] present would be:

moles of [tex]HNO_{3}[/tex] = 4 mol/L × 0.5 L = 2 moles

Therefore, 2 moles of [tex]O_{2}[/tex] gas and 1 mole of [tex]NO_{2}[/tex] gas would be produced from 2 moles of [tex]HNO_{3}[/tex] during electrolysis.

It's worth noting that the oxidation of nitric acid to form nitrogen dioxide is an exothermic reaction that can produce heat, so the electrolysis may need to be performed under controlled conditions to prevent overheating.

A: begin to cool and daylight hours decrease.

Plants go through seasonal changes from summer to fall because of the changes in temperature and the length of daylight hours. As summer ends and fall begins, temperatures begin to cool down and the days become shorter. This change in temperature and daylight hours triggers physiological changes in plants, such as the slowing down of growth and the production of pigments like anthocyanins, which give leaves their characteristic red and orange colors in the fall. These changes allow the plant to prepare for the colder winter months and conserve energy for the upcoming spring growth season.

According to the question the reaction enthalpy is thus 10610 J / 0.278 moles = 38.3 kJ/mol.

Enthalpy is a thermodynamic property of a system that measures the total energy content of a system. It is a state function that is expressed in terms of internal energy, pressure, and volume of a system. Enthalpy represents the amount of energy that is associated with a chemical reaction or physical change.

The reaction is exothermic, meaning that heat is released during the reaction. The amount of heat released can be calculated with the equation q = mcΔT, where q is the heat released, m is the mass of the solution, c is the specific heat capacity of the solution, and ΔT is the change in temperature of the solution. Using the given data, the amount of heat released by the reaction can be calculated as q = (250 g)(4.184 J/g-K)(11.1 K) = 10610 J. The enthalpy change for the reaction can then be calculated by dividing the heat released by the number of moles of NaOH, which is 11.1 g / 40.00 g/mol = 0.278 moles. The reaction enthalpy is thus 10610 J / 0.278 moles = 38.3 kJ/mol.

At 25°C, combine 47.0 mL of ethylene glycol (d = 1.11 g/mL; molar mass = 62.07 g/mol) with 50.0 mL of water (d = 1.00 g/mL) to create an antifreeze solution. The antifreeze solution's molarity is 0.0086 M if its density is 1.07 g/mL.

Antifreeze is an additive that reduces a water-based liquid's freezing point. To achieve freezing-point depression for cold conditions, an antifreeze combination is utilized. Common antifreezes also raise the liquid's boiling point, enabling a rise in coolant temperature. However, every typical antifreeze addition also has a lower heat capacity than water, which makes it less effective as a coolant when combined with water.

The combination of a solution's freezing and boiling temperatures depends on the amount of dissolved components present. Therefore, salts cause aqueous solutions' melting points to decrease. Although salts are widely used for de-icing, salt solutions should not be utilized in cooling systems as they cause metal corrosion. Because they typically have melting values that are lower than those of water, low molecular weight organic substances can be used as antifreeze. Alcoholic organic compound solutions, in particular, are useful. Since antifreezes were first made commercially available in the 1920s, they have all been composed primarily of alcohols such methanol, ethanol, ethylene glycol, and others.

Molarity = [tex]\frac{mole}{volume}[/tex]

To calculate the moles of ethylene glycol.

The mass of ethylene glycol is 47.0 mL × 1.11 g/mL = 52.17 g.

Since molar mass of ethylene glycol is 62.07 g/mol, the moles of ethylene glycol is:

[tex]\frac{52.17}{62.07}[/tex] = 0.84 mol

To calculate the total volume of the antifreeze solution. We know that the volumes of ethylene glycol and H₂O are 47.0 mL and 50.0 mL, respectively.

Therefore, the total volume of the antifreeze solution is 47.0 mL + 50.0 mL = 97.0 mL.

Finally, the molarity of the antifreeze solution can be calculated using the formula

Molarity = [tex]\frac{mole}{volume}[/tex]

Therefore, the molarity of the antifreeze solution is:

a. Wax melts near the flame of a burning candle because the kinetic-molecular theory states that the higher the temperature, the faster the molecules move. Since the flame of a burning candle is hot, the wax molecules move faster, allowing them to take up more space and eventually melt.

The kinetic-molecular theory is based on the following five fundamental principles:

A gas's average molecular lengths between its constituent molecules are significantly greater than their individual sizes. The volume occupied by the gas' molecules is negligible in comparison to the volume of the gas itself.Both the molecules and the container walls are not attracted to one another in a perfect gas.As physical objects, the molecules move erratically and continually and are governed by Newton's laws of motion. The molecules travel in a straight line until they come into contact with one another or the container walls. Collisions are totally elastic; even if the kinetic energies and orientations of two molecules may change during a collision, the total kinetic energy is preserved. Collision is not "sticky".The average gas molecule's kinetic energy and absolute temperature are directly correlated. Because individual molecules' velocities and kinetic energies will vary greatly, with some even experiencing zero velocities at some moments, the word "average" is significant in this context. This implies that all molecular motion would cease if the temperature dropped to absolute zero.

b. Due to the fact that the kinetic-molecular theory predicts that molecules move more slowly at lower temperatures, liquid water can be frozen into ice cubes in a freezer. The water molecules travel very slowly and arrange because a freezer is significantly colder than room temperature, which enables them to form ice cubes.

c. All matter is made up of a large number of tiny particles that are always in motion, according to the kinetic-molecular theory. When the ginger ale is poured into the glass, the velocity of the liquid's molecules causes them to spread out and fill the form of the vessel.

d. The kinetic-molecular theory states that the molecules in a liquid are in constant motion, and that when they move, they bump into each other, passing energy from one to the other. This energy causes the particles to move faster. As they move faster, they create turbulence that causes them to break away from the liquid surface. These particles then form a vapor, which is an invisible form of water called water vapor. As these particles accumulate together, they gradually evaporate from the swimming pool, eventually diminishing its water level.

e. Water vapor condenses inside house windows on cold days because the molecules of water vapor slow down and as they lose energy they no longer have enough kinetic energy to remain in the gaseous state. The molecules then condense and form liquid water droplets on cool surfaces such as windows.

f. Snow gradually disappears even when the temperature remains below freezing because the heat stored in the snow starts to melt the snow. This occurs even when the outside temperature remains at freezing or below because the heat is released from the snow and warms the surrounding air.

g. Solids and liquids cannot be compressed as much as gases because the particles of gases have more energy and thus more freedom of movement than particles of solids and liquids. The particles of gases can move around and can occupy larger spaces than particles of solids and liquids, allowing them to be compressed more effectively.

According to the question, there are 5.857 x 10¹¹ molecules of C₁₂H₂₂O₁₁ in 205g of sucrose.

Molecules are the building blocks of all matter. They are composed of one or more atoms that are held together by covalent bonds, which are formed when electrons are shared between atoms. Molecules can exist as individual entities, but they often combine with other molecules to form larger structures, such as proteins, carbohydrates, and lipids. Molecules can also be found in all living things, from the smallest bacteria to the largest mammals.

This is calculated by taking the molecular weight of sucrose (342.34 g/mol) and dividing it by 205, the mass of the sucrose. This yields a ratio of 1 mol sucrose/ 1.6943 g sucrose. Multiplying this ratio by 205 yields 342.34 mol sucrose, which when multiplied by Avogadro's Number (6.022 x 10²³ mol) yields 5.857 x 10¹¹ molecules of C₁₂H₂₂O₁₁.
