Answer:
In chemistry, a mixture is a substance made up of 2 or more substances that are not chemically combined, but physically combined. This means there are no chemical bonds between the different substances in a homogeneous or heterogeneous mixture. You can think of a salad as an example of a mixture— lettuce, tomatoes, cucumbers, and Parmesan cheese are substances, and each substance retains its own chemical composition and identity.
A homogeneous mixture (from the root “homo” meaning same) has a uniform composition throughout. Furthermore, in a homogeneous mixture, all substances exist in one state of matter. Liquids can be homogeneously mixed with liquids, solids with solids, and so on.
Examples :
1)Saltwater
If salt dissolves in water, it disperses evenly throughout the water. Note that seawater can be heterogeneous if pieces of particulate matter are present, as in nature.
2)Coffee, milk
These drinks consist of many chemicals dissolved in water, spread evenly like in saltwater. However, when milk curdles, it becomes a heterogeneous mixture.
3)Cement, glue
These are homogeneous mixtures of chemicals that set (harden) on drying or exposure to other special conditions. They may have other things added which could make them heterogeneous.
4)Bronze, steel
These are alloys, made by mixing copper and tin (for bronze) or iron and carbon (for steel). Because the resulting mixtures do not have distinguishable regions of each component, they are homogeneous.
5)Air
Air is a mixture of gases spread evenly throughout the atmosphere. Because gas molecules are distant from one another, they always mix evenly and do not form heterogeneous mixtures.
Other examples include :
6)Mouthwash
7)Detergent
8)Cologne
9)Jello gelatin
10) Sugar syrup

Part A) Using your graduated cylinder, you calibrate the pipet you will be using and the values you collect are as follow. What is the average number of drops per mL of benzene.
21 drops 20 drops 17 drops Answer: 19.3 drops
Part B) After calibration, you use the oleic acid/benzene solution to form a monolayer. It takes 8 drops , 9 drops and 8 drops before the layer on the water solution starts to make a bubble tha does not go into solution. What is the average number of drops for your monolayer?
Answer: 8.33 drops
Part C) Since we have the number of drops it takes to make a monolayer and we have the number of drops it takes to make one mL of benzene, we can determine the mL of oleic acid/benzene it takes to form a monolayer.
Answer: 0.431 mL
Part D) Next we need to determine the mass of oleic acid in the monolayer. The concentration of the oleic acid/benzene solution is 0.02g/L. Calculate how many grams of oleic acid is in one drop.
Part E) sWith this information, we now need to calculate the volume in milliliters. We need to know how many mLs a drop of oleic acid occupies using the density of 0.895 g/mL and the number of drops of oleic acid solution used.
Part F) Determine the volume of the monolayer from the above information.
ANSWERS NEEDED FOR PARTS D, E, AND F
Answers for parts D, E and F are (D) Mass of oleic acid in one drop =1.036 x 10⁻⁶ g/drop. (E) 1.157 x 10⁻⁶mL/drop (F) Volume of monolayer = 9.632 x 10⁻⁶ mL.
Part D) To calculate the mass of oleic acid in one drop, we first need to calculate the mass of oleic acid in one mL of the solution.
Concentration of oleic acid/benzene solution = 0.02 g/L
Therefore, 1 L of solution contains 0.02 g of oleic acid.
As 1 L = 1000 mL, 1 mL of solution contains 0.02/1000 = 0.00002 g of oleic acid.
We know that 1 mL of benzene contains 19.3 drops, so the mass of oleic acid in one drop of the solution can be calculated as:
Mass of oleic acid in one drop = (0.00002 g/mL) / (19.3 drops/mL)
= 1.036 x 10⁻⁶ g/drop
Part E) The density of oleic acid is given as 0.895 g/mL. To calculate the volume of one drop, we need to know the mass of one drop of oleic acid. We can use the mass of oleic acid in one drop calculated in Part D to find the volume of one drop.
Mass of one drop of oleic acid = 1.036 x 10⁻⁶ g/drop
Volume of one drop = (Mass of one drop of oleic acid) / (Density of oleic acid)
= (1.036 x 10⁻⁶ g) / (0.895 g/mL)
= 1.157 x 10⁻⁶ mL/drop
Part F) The number of drops used to form a monolayer is given as 8.33 drops. Using the volume of one drop calculated in Part E, we can find the volume of the monolayer.
Volume of monolayer = (Number of drops used) x (Volume of one drop)
= (8.33 drops) x (1.157 x 10⁻⁶ mL/drop)
= 9.632 x 10⁻⁶ mL

c) The volume of a hydrogen atom in cubic angstroms is approximately 0.704 Å^3.
What do you mean by hydrogen?
Hydrogen is the chemical element with the symbol H and atomic number 1. It is the most abundant element in the universe, making up about 75% of its elemental mass. Hydrogen is a colorless, odorless, and tasteless gas, and it is the lightest element in the periodic table.
Hydrogen has a number of important industrial applications, including use in the production of ammonia, methanol, and other chemicals. It is also used as a fuel for rockets and other forms of transportation, and is being explored as a potential energy source for powering vehicles and homes. In its liquid and solid forms, hydrogen is used as a coolant in nuclear reactors.
The volume of a hydrogen atom can be calculated using the formula for the volume of a sphere:
V = (4/3) * π * r^3
where r is the radius of the hydrogen atom.
The radius of a hydrogen atom is approximately 0.53 angstroms, so we can substitute this value into the formula and calculate the volume in each unit:
(a) cubic picometers:
1 pm = 10^-3 angstroms
V = (4/3) * π * (0.53 angstroms)^3 = 0.704 cubic angstroms
V in pm^3 = 0.704 * (10^-3 angstroms/pm)^3 = 0.704 * 10^-27 pm^3
Therefore, the volume of a hydrogen atom in cubic picometers is approximately 0.704 * 10^-27 pm^3.
(b) cubic nanometers:
1 nm = 10 angstroms
V = (4/3) * π * (0.53 angstroms)^3 = 0.704 cubic angstroms
V in nm^3 = 0.704 * (10 nm/angstroms)^3 = 0.704 * 10^-27 nm^3
Therefore, the volume of a hydrogen atom in cubic nanometers is approximately 0.704 * 10^-27 nm^3.
(c) cubic angstroms:
V = (4/3) * π * (0.53 angstroms)^3 = 0.704 cubic angstroms
Therefore, the volume of a hydrogen atom in cubic angstroms is approximately 0.704 Å^3.

How do electrons from an ion and cation interact in an ionic bond? Why do these ionic bonds have such a high lattice energy, that is, why do ionic bonds require so much energy to break?
Ionic bonds form when electrons from an ion (a negatively charged atom) interact with an cation (a positively charged atom).
The electron from the ion is attracted to the cation, and the cation is attracted to the electron. This attraction causes the two atoms to bond together, forming an ionic bond. These have a high lattice energy because of the strong electrostatic attraction between the ions. The attraction between the ions is caused by their opposite charges, and this strong attraction requires a lot of energy to break the bond. The lattice energy is the energy required to separate two ions into their individual gaseous states. The stronger the attraction between the ions, the higher the lattice energy.

colligative properties depend only on solute concentration; the identity of the solute is not important. true/false
False. This statement is generally true for ideal solutions, which are solutions that follow Raoult's law.
According to Raoult's law, the vapor pressure of a solution is directly proportional to the mole fraction of the solvent in the solution. Colligative properties, such as boiling point elevation, freezing point depression, and osmotic pressure, are all related to changes in the vapor pressure of a solution. Since Raoult's law assumes that the solute molecules do not interact with the solvent or with each other, the identity of the solute does not affect the vapor pressure or the colligative properties of the solution. However, real solutions may deviate from Raoult's law due to interactions between the solute and solvent molecules, and in those cases, the identity of the solute can affect the colligative properties.
