describe the form of the equilibrium constant expression in terms of the concentrations of the reactants and products
The equilibrium constant, Kc, is the ratio of the equilibrium concentrations of products over the equilibrium concentrations of reactants each raised to the power of their stoichiometric coefficients.
For a reaction: aA + bB→ cC + dD
Equilibrium constant: Kc=[tex][C]^{c}[D]^{d}[/tex]/ [tex][A]^{a} [B]^{b}[/tex]
Characteristics of Kc:
1) Equilibrium can be approached from either direction.
2) Kc does not depend on the initial concentrations of reactants and products.
3) Kc does depend on temperature.
Magnitude of Kc:
1) If the Kc value is large (Kc >> 1), the equilibrium lies to the right and the reaction mixture contains mostly products.
2) If the Kc value is small (Kc <<1), the equilibrium lies to the left and the reaction mixture contains mostly reactants.
3) If the Kc value is close to 1 (0.10 < Kc < 10), the mixture contains appreciable amounts of both reactants and products.

What is ideal gas law?The ideal gas is the virtual gas that chemists and students dream of because it would be much simpler if there weren't some kind of intermolecular force that would complicate the simple law of the ideal gas. An ideal gas is essentially a point cloud moving with constant random linear motion. Its behavior is described by the assumptions described in the kinetic molecular theory of gases. This ideal gas definition contrasts with the non-ideal gas definition. This is because this equation describes how gases actually behave.
The ideal gas law states that the product of pressure and volume in a gram molecule of an ideal gas is equal to the product of the gas's absolute temperature and the universal gas constant.
PV = nRT
Where, n = number of moles.
P = Pressure (1 atm)
T = Temperature (273 K)
V = Volume (0.5 L)
R = Ideal gas constant (8.314J/K⋅mol)
Now, substitute the values:
1 × 0.5 = n × 8.314 × 273
n = 0.00022 moles
Mg + 2HCl → MgCl₂ + H₂
The mole ratio of Mg and H₂ is 1:1 for the given reaction
Hence the number of moles for Mg will be same as H₂, which is 0.00022 moles.
For the mass of Mg:
m = n × Mm
Where, m = mass
n = number of moles (0.00022 moles)
Mm = molar mass (24.3 g/moles)
m = 0.00486 g

If I have 2.9 L of gas at a pressure of 5.0 atm and a temperature of 50.0 °C, what will be the temperature of the gas if I decrease the volume of the gas to 2.4 decrease the pressure to 3.0 atm?
According to the ideal gas law, the relationship between the pressure, volume, and temperature of a gas is given by the equation PV = nRT, where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas in Kelvin.
If we have 2.9 L of gas at a pressure of 5.0 atm and a temperature of 50.0 °C, we can calculate the temperature of the gas if we decrease the volume of the gas to 2.4 and decrease the pressure to 3.0 atm by rearranging the ideal gas law equation as follows:
T = (PV) / (nR)
In this equation, T represents the temperature of the gas, P represents the pressure of the gas, V represents the volume of the gas, n represents the number of moles of gas, and R represents the ideal gas constant.
Plugging in the values from the problem into the equation, we get:
T = (5.0 atm * 2.9 L) / (n * 0.08206 L*atm / mol*K)
T = (14.5 L*atm) / (n * 0.08206 L*atm / mol*K)
T = (14.5 L*atm) / (n * 0.08206 L*atm / mol*K)
T = 177.2 K
Therefore, if we have 2.9 L of gas at a pressure of 5.0 atm and a temperature of 50.0 °C, and we decrease the volume of the gas to 2.4 and decrease the pressure to 3.0 atm, the temperature of the gas will be 177.2 K.
if the combustion of 42.62 g of c4h10 produces 87.85g of co2. what is the percent yield of the reaction? (assume oxygen is in excess.)
The balanced chemical equation for the combustion of C4H10 is C4H10 + 6O2 → 4CO2 + 5H2O.
So,
The moles of C4H10 consumed in the reaction is 42.62 g / (58.12 g/mol) = 0.732 mol.
The moles of CO2 produced in the reaction is 87.85 g / (44.01 g/mol) = 1.99 mol.
The percent yield of the reaction is (1.99 mol CO2 / 0.732 mol C4H10) x 100% = 271.7%.

The mass per cent of Zn in the mixture is 22%.
What is Mass percent?Mass percent is a means to describe a component in a specific combination or to convey a concentration. The mass percentage used to describe the solution composition indicates the mass of solute contained in a given mass of solution. The solute's concentration is specified in terms of mass or moles. The mass percent of a solution is calculated by multiplying the grams of solute per gram of solution by 100 to get the percentage.
What are the calculations?mass of the mixture = 3.0 g
moles of ZnO in the mixture = 0.010 mol
mass of ZnO in the mixture = moles × molar mass
= 0.010 mol × 81.38 g/mol
= 0.8138 g
now mass percent of ZnO in the mixture = mass of (ZnO/Total mass) × 100.
27%
now, 81.38 g of ZnO contains = 65.38 g of Zinc.
0.8138 g of ZnO contains = (65.38 / 81.38) × 0.813 g
= 0.6538 g.
so, mass % of Zn in the mixture = (Mass of Zn/ Total Mass) × 100
