What happens when you try to heat up a substance that has a high specific heat?

Answers

When you try to heat up a substance that has a high specific heat, it will require a lot of energy to raise its temperature. This is because substances with high specific heat have a greater ability to absorb heat energy without undergoing a significant temperature change.

For example, water has a high specific heat, which means it can absorb a lot of heat energy before its temperature increases significantly. This is why water is commonly used to regulate temperature in various applications, such as in cooling systems or in living organisms that need to maintain a stable internal temperature.

So, if you try to heat up a substance with a high specific heat, you will need to supply a large amount of heat energy to cause a noticeable increase in temperature. Conversely, if you try to cool down the same substance, it will release a large amount of heat energy before its temperature decreases significantly.

Specific heat is the amount of heat energy required to raise the temperature of a substance by a certain amount, usually one degree Celsius or Kelvin. Different substances have different specific heat values, and these values depend on the physical and chemical properties of the substance.

39. a compound of carbon and hydrogen contains 92.3% c and has a molar mass of 78.1 g/mol. what is its molecular formula?

Answers

The molecular formula of the compound is (CH)6 or C6H6

Molecular formula calculation.

To determine the molecular formula of a compound from its percentage composition and molar mass, we can follow these steps:

Convert the percentage composition of each element into its corresponding mass.

The compound contains 92.3% C and 7.7% H. Assuming a 100-g sample of the compound, the mass of C is:92.3 g C = (92.3/100) x 100 g sample = 92.3 g

The mass of H is:

7.7 g H = (7.7/100) x 100 g sample = 7.7 g

Calculate the number of moles of each element

The number of moles of C is:

n(C) = m(C) / M(C)

n(C) = 92.3 g / 12.01 g/mol = 7.689 moles

The number of moles of H is:

n(H) = m(H) / M(H)

n(H) = 7.7 g / 1.008 g/mol = 7.639 moles

Divide the number of moles of each element by the smallest number to obtain the simplest whole-number ratio of the elements.

Dividing both values by 7.639, we get:

n(C) = 1.007

n(H) = 1.000

Rounding these values to the nearest whole number, we get:

Therefore, the empirical formula of the compound is CH.

Now, we need to determine the molecular formula by finding the factor by which the empirical formula must be multiplied to get the molar mass of 78.1 g/mol.

The molar mass of the empirical formula CH is 12.01 g/mol + 1.01 g/mol = 13.02 g/mol.

Dividing the molar mass of the compound by the molar mass of the empirical formula gives us the factor by which the empirical formula must be multiplied:

78.1 g/mol ÷ 13.02 g/mol ≈ 6

Therefore, the molecular formula of the compound is (CH)6 or C6H6 after getting the empirical formula.

how many different kinds of h signals would be observed in the h-nmr in 2-methylcyclohexanol?

Answers

The H-NMR spectrum of 2-methylcyclohexanol would typically show at least three different H signals, corresponding to the OH proton, the methyl group, and the ring protons.

What is nuclear magnetic resonance (H-NMR) spectrum?

The nuclear magnetic resonance (NMR) spectrum is a spectroscopic technique used to determine the molecular structure of a compound by analyzing the magnetic properties of its atomic nuclei.

In proton nuclear magnetic resonance (H-NMR) spectroscopy, the magnetic properties of the hydrogen nuclei (protons) in a molecule are measured. The technique is based on the principle that when a molecule is placed in a strong magnetic field, the protons align themselves either with or against the magnetic field, resulting in two possible spin states.

In the proton nuclear magnetic resonance (H-NMR) spectrum of 2-methylcyclohexanol, the number of different H signals (peaks) observed depends on the different types of proton environments present in the molecule.

2-methylcyclohexanol has several types of protons, which will produce distinct peaks in the H-NMR spectrum:

The OH proton will appear as a broad peak around δ 2.5-5.0 ppm due to its exchange with solvent protons.

The methyl (CH3) group on the cyclohexane ring will produce a singlet peak around δ 0.9-1.0 ppm.

The five protons on the cyclohexane ring will produce a complex splitting pattern, depending on their position and neighboring atoms.

In general, if the methyl group is located in an equatorial position, the ring protons will appear as two triplets (due to coupling with the neighboring axial protons) and one multiplet (due to coupling with the other ring protons). If the methyl group is located in an axial position, the ring protons will appear as a broad multiplet.

Therefore, the H-NMR spectrum of 2-methylcyclohexanol would typically show at least three different H signals, corresponding to the OH proton, the methyl group, and the ring protons.

Answers

The Molar mass concept helps to determine the moles of substance fir provide mass of substance. The oxygen atoms present in 52.06 g of carbon dioxide are equals to 1.424 ×10²⁴. So, correct answer is option (c).

Molar mass is the mass of one mole of a substance in grams of that substance. Molar mass is determined using atomic mass values from the periodic table. The atomic mass is written in atomic mass units, and molar mass is written in grams. Now the mass of carbon dioxide =52.06 g

The molar mass of carbon dioxide, M= 2×16 g/mol + 12 g/mol = 32 g/mol + 12.

01 g/mol = 44.01 g/mol

We can now solve this problem by converting 52.06 g of carbon dioxide to moles of carbon dioxide. Avogadro's number (6.022×10²³) into carbon dioxide molecules. Finally multiply by 2. Because every carbon dioxide molecule has two oxygen atoms.

= (52.06 g CO₂) × (1 mol CO₂)/44.1 g CO₂) × (6.022×10²³ CO₂ molecules/1 mol CO2)× (2 Oxygen atoms/1 CO₂ molecule)

= 1.424×10²⁴ oxygen atoms.

a) The theoretical yield of H2O is 16.25 grams.

b) The actual yield of H2O is 13.81 grams

The Propane Combustion Yield.

First, balance the equation

C3H8 + SO2 → 3CO2 + 4H2O

a) To calculate the theoretical yield of H2O when starting with 10 grams of C3H8, we first need to determine the limiting reagent. This is the reactant that will be completely consumed in the reaction, thereby limiting the amount of product that can be formed.

The molar mass of C3H8 is 44.1 g/mol,

so 10 grams of C3H8 is equivalent to 10/44.1 = 0.226 moles of C3H8.

The molar mass of SO2 is 64.1 g/mol. We don't know how much SO2 we have, so we need to use stoichiometry to determine the amount required to react with 0.226 moles of C3H8.

From the balanced equation, we can see that the molar ratio of C3H8 to SO2 is 1:1.

Therefore, we need 0.226 moles of SO2 to react with 0.226 moles of C3H8.

The molar ratio of H2O to C3H8 is 4:1.

So if 0.226 moles of C3H8 react, we can expect to produce 4 times as many moles of H2O.

The molar mass of H2O is 18.0 g/mol, so the theoretical yield of H2O is:

0.226 mol C3H8 × 4 mol H2O/mol C3H8 × 18.0 g/mol H2O

= 16.25 g H2O

Therefore, the theoretical yield of H2O is 16.25 grams.

b) If the actual yield of H2O is 85% of the theoretical yield, then the actual amount of H2O produced is:

0.85 × 16.25 g = 13.81 g

Therefore, the actual yield of H2O is 13.81 grams.

C) the size of the sample doesn't affect the mp measurement

Answers

Answer:

B) the sample should not be large, because a large sample would produce a higher and broader mp range.

The size of the sample can have an effect on the melting point measurement. Using a large sample size can lead to a higher and broader melting point range, making it more difficult to accurately determine the melting point of the substance. This is because a larger sample will take longer to heat uniformly, resulting in a less precise melting point measurement. Additionally, a larger sample may contain impurities that can affect the melting point range. Therefore, it is recommended to use a small sample size when measuring the melting point of a substance to obtain accurate and precise results.

What type of bcl3 ? polar or nonpolar?

Answers

The chemical boron trichloride (BCl3) is nonpolar. The molecule has a trigonal planar structure, with three chlorine atoms surrounding the central boron atom.

In BCl3, three chlorine atoms form covalent connections with the boron atom. While chlorine has seven valence electrons, boron's valence shell only has three. Boron thus forms three single covalent connections with three chlorine atoms by sharing its three valence electrons with them. The three B-Cl bonds are all polar because chlorine has a stronger electronegativity than boron. The three chlorine atoms are, however, symmetrically positioned around the primary boron atom because the molecule has a trigonal planar geometry and is symmetrical. This configuration causes the three B-Cl bonds' dipole moments to cancel out, resulting in a net dipole moment of zero. As a result of its lack of polar bonds, BCl3 is regarded as a nonpolar molecule.

Calculate the mass of oxygen gas required tooccupy a volume of 6 L at a pressure of 20.9kPa and a temperature of 37◦C.1. 0.779 g2. 1.56 g3. 0.408 g4. 13.1 g5. 0.0487 g

Answers

The mass of oxygen gas required to occupy a volume of 6 L at a pressure of 20.9 kPa and a temperature of 37°C is 0.155 g, which is closest to option 2 (1.56 g). Option 2 is correct.

To solve this problem, we can use the ideal gas law, which relates the pressure, temperature, volume and the number of moles of a gas:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, as well as T is the temperature. We rearrange this equation to solve for the number of moles of gas:

n = PV/RT

We know the pressure (20.9 kPa), volume (6 L), temperature (37°C = 310 K), and we are looking for the number of moles of oxygen gas. The gas constant R is 8.31 J/(mol·K). Molar mass of oxygen gas (O₂) will be 32 g/mol.

n = PV/RT = (20.9 kPa)(6 L)/(8.31 J/(mol·K) × 310 K)

= 0.00487 mol

To calculate the mass of oxygen gas, we can use the molar mass:

mass = n × molar mass

= 0.00487 mol × 32 g/mol

= 0.155 g

Hence, 2. 1.56 g is the correct option.

__________ structure influences how atoms are bonded together

Answers

Atomic structure influences how atoms are bonded together.  Atomic derives from the Latin atoms, "indivisible particle," from the Greek atomos, "uncut" or "indivisible." Adjective of, pertaining to, or consisting of atoms is defined as "atomic."

The fundamental unit of chemistry is the atom. It is the smallest particle that can be separated into the matter without releasing electrically charged particles. Moreover, it is the smallest piece of matter with the characteristics of a chemical element.

Quarks and electrons, two different types of basic particles, make up atoms. The area around the nucleus of an atom is filled with electrons. A single electron has a -1 electrical charge. Protons and neutrons are made of quarks, and the nucleus of an atom is made up of these particles.

which equation represents the integrated rate law for a zero-order reaction?
a. at=-kt+a0
b. 1/a=kt+1/a0
c. t=.693/k
d. lna=-kt+lna

Answers

The equation represents the integrated rate law for the zero-order reaction is at = - kt + a0. The correct option is a.

The integrated rate equation for the zero-order reactions is the equation name given to the equation. The integrated rate law for a zero-order reaction is as follows :

at = - kt + a0

The above equation is the equation that is known as the integrated rate equation for the zero order reactions. The zero - order reaction is the one whose rate is the independent of the concentration, its the differential rate law that is rate = k. This refer to the reactions as the zero order because we could also write the rate in the form such that the reactant in the rate law is the 0. Therefore, option a is correct.
