First, we have to remember what a mass percentage means (in this particular case):
It is the amount of each element in a compound, and it is calculated as follows:
[tex]\%\text{ m/m = }\frac{mass\text{ of the element}}{mass\text{ of the compound}}*100\text{ }[/tex]The addition of the different mass percentages is equal to 100%.
In this case, we have the percentage of one of the elements of the compound, we can make the respective subtraction:
[tex]\%I\text{ = 100 - 13.6 = 86.4 \%}[/tex]Then, the answer is that the iodine mass percentage is 86.4%
If 21.5 g of LiCl are dissolved 450.0 g of water at 20.0 °C in an insulated container, a temperature change is observed. The ∆H of solution of LiCl is -37.0 kJ/mol. Assuming that the specific heat of the solution is 4.184 J/(g°C), and that no heat is gained or lost by the container, what will be the final temperature of the solution?
The final temperature of the solution will be 29.5 °C.
What is the heat released when 21.5 g of LiCl is dissolved completely in water?The heat released when 21.5 g of LiCl is dissolved completely in water is determined from the enthalpy change, ∆H of the solution of LiCl as follows;
Moles of LiCl in 21.5 g = mass/ molar mass
molar mas of LiCl = 42.5 g/mol
Moles of LiCl in 21.5 g = 21.5/42.5
Moles of LiCl in 21.5 g = 0.506 moles
Heat released = 0.506 * -37.0 kJ/mol
Heat released = 18.722 kJ or 18722 J
Heat released = heat gained by solution
Temperature change of the solution = heat gained / mass * specific heat capacitymass of solution = 450 + 21.5
mass of solution = 471.5 g
Temperature change of the solution = 18722 / (471.5 * 4.184)
Temperature change of the solution = 9.5 °C
Final temperature of the solution = 20 °C + 9.5 °C
Final temperature of the solution =29.5 °C

What kind of intermolecular forces act between a chloramine (NH₂CI) molecule and an oxide (0²-) anion?Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between thename of each force.
Answer
Hydrogen bonding, dipole-dipole interaction, and dispersion forces.
Explanation
The chloramine (NH₂CI) molecule has N-H bonds, so there will be hydrogen bonding. Also, NH₂Cl is a polar molecule, so there will be dipole-dipole interaction. And as with molecules like O²⁻, there will be dispersion forces.
Therefore, the kind of intermolecular forces that act between a chloramine (NH₂CI) molecule and an oxide (O²⁻) anion are hydrogen bonding, dipole-dipole interaction, and dispersion forces.
2. 5.4 grams of carbon dioxide gas is confined to a 20.0 L container at atemperature of 32.5°C. What pressure does the gas exert? (15 kPa)
To calculate this, we will need to assume the gas behaves as an ideal gas.
So, we can use the Ideal Gas Law:
[tex]PV=nRT[/tex]Where P is the pressure, V is the volume, n is the number of moles, is the absolut temperature and R is the gas law constant.
Since we have carbon dioxide, CO₂, we need to calculate its molar mass to convert the mass to number of moles:
[tex]\begin{gathered} M_{CO_2}=(1\cdot M_C+2\cdot M_O) \\ M_{CO_2}=(1\cdot12.0107+2\cdot15.9994)g\/mol \\ M_{CO_2}=44.0095g\/mol \end{gathered}[/tex]So, the number of moles is:
[tex]\begin{gathered} M_{CO_2}=\frac{m}{n} \\ n=\frac{m}{M_{CO_{2}}}=\frac{5.4g}{44.0095g\/mol}=0.1227\ldots mol\approx0.12mol \end{gathered}[/tex]Also, we need to convert the temperature to absolute temperature, so we can convert it to K by adding 273.15 to the degree celcius temperature:
[tex]T=32.5\degree C=(32.5+273.15)K=305.65K[/tex]Now, we need to use the constant R that has the unit we want. We have K for temperature, mol for number of moles and L for volume. Is we want the pressure in kPa, we need to use the R constant with units L*kPa/(K*mol), which have the value:
[tex]R\approx8.31446\frac{L\cdot kPa}{K\cdot mol}[/tex]So, solving the equation for P and substituting the values, we have:
[tex]\begin{gathered} PV=nRT \\ P=\frac{nRT}{V} \\ P=\frac{0.12mol\cdot8.31446L\cdot kPa\cdot K^{-1}mol^{-1}\cdot305.65K}{20.0L} \\ P=\frac{0.12\cdot8.31446\cdot305.65}{20.0}kPa \\ P=15.247\ldots kPa\approx15kPa \end{gathered}[/tex]So, the pressure is approximately 15 kPa.

What is ideal gas equation?Ideal gas equation is defined as the state equation for a fictitious perfect gas. Although it has significant drawbacks, it is a decent approximation of the behavior of many gases under various conditions.
Ideal gas equation is expressed as
PV = nRT
By using Ideal gas equation
P x 0.016773 = 1 x 81.49 x 483
P = 1.861 MPa
By using generalized compressibility chart
For r134a
Temperature = 374.2 K
Pressure = 4.06 MPa
vR = V / R x Tc / Pc
= 0.016773 / 81.49 x ( 374.2 / 4.06 x 10⁶ )
= 2.2332
Tr = T/Tc = 383 / 374.2 = 1.024
Therefore from the chart Z = 0.85
So, P = Z mRT / V
P = 0.85 x 1 x 81.49 x 383 / 0.016773
= 1.582 MPa
By using refrigerant tables
T = 110 C and v = 0.0167763

To calculate the number of atoms of any compound it is necessary to use the Avogadro constant. This is a constant of proportion between the amount of matter and the number of entities that are linked to that amount. These entities can be atoms, molecules, ions, electrons, protons, neutrons. The value of the Avogrado constant is 6.022 x 10^23 mol^-1.
So to calculate the number of atoms in 275 grams of iron (III) hydroxide:
- First you need to transform grams into moles
- transform moles into atoms/molecule using Avogrado constant.
- To transform 275 grams of Fe(OH)₃ you need to use the molecular mass of Fe(OH)₃ and the following equation: mole = mass/molar mass

A -13.68 gram of sample of iron is heated in the presence of excess fluorine. A metal Fluoride is formed with a mass of 27.64g. Determine the empirical formula of the metal fluoride.
Explanation:
A 13.68 g sample of iron is reacted in presence of excess fluorine and an iron fluoride with a mass of 27.64 g is formed.
We have to find the empirical formula of our compound. This compound has two elements: Fe and F. We can express it like:
metal fluoride = FeₐFₓ
Where a is the subscript of Fe and x is the subscript for F.
First we have to find the mass of F present in the compound. We know that our compound has a total mass of 27.64 g and the mass of Fe present is 13.68 g. Since it only has two elements we can find the mass of F.
mass of sample = mass of Fe + mass of F
mass of F = mass of sample - mass of Fe
mass of F = 27.64 g - 13.68 g
mass of F = 13.96 g
So we found that our sample has 13.96 g of F and 13.68 g of Fe. Now we can determine the number of moles of each element that are present in the sample by using their molar masses.
molar mass of Fe = 55.85 g/mol
molar mass of F = 19.00 g/mol
moles of Fe = 13.68 g * 1 mol/(55.85 g)
moles of Fe = 0.245 moles
moles of F = 13.96 g * 1 mol/(19 g/mol)
moles of F = 0.735 moles
By definition the empirical formula is "simplest whole number ratio of atoms present in a compound". So if we want to find the ratio between them we have to divide both of them by the smallest number.
a = subscript of Fe = 0.245/0.245 = 1
x = subscript of F = 0.735/0.245 = 3
So the empirical formula of our compound is:
empirical formula = FeₐFₓ
empirical formula = FeF₃
Answer: empirical formula = FeF₃

The electron has an intrinsic angular momentum of a half-integer number and has a mass that is around 1/1836th that of the proton. The quantum state of any two electrons cannot be identical.
The chemical reaction for solid zinc is
Zn²⁺ + 2e⁻ = Zn (s)
When one mole of zinc ions receive two moles of electrons, one mole of zinc is created.
Electrons equal two moles to form one mole of solid zinc.
The electrons needed to create the 53.5 mole of zinc will provide 2 53.5 = 107 mol.
Thus, the moles of electrons are needed to produce 53.5 mole of Zn is 107 moles.
