What volume of hydrogen will be produced at stp by the reaction 55.5 grams of magnesium with excess water according to the following reaction

Methane (CH4), the principal constituent of natural gas, reacts with oxygen

according to this equation:

CH4 + 2 O2 → CO2 + 2 H2O

How many grams of O2 are needed to produce 37.5 g of CO2?

Given the equation,

Mg(OH)2 + 2 HCl → MgCl2 + 2 H2O

Assume that a person takes 0.100 g Mg(OH)2. How many mol of MgCl2 will be produced from the ingested antacid, assuming all of the antacids undergo the reaction?

Given the equation, solve the following problems:

C6H12O6 → 2 C2H5OH + 2 CO2

a. How many mol of C2H5OH is formed by the complete reaction of

C6H12O6?

b. How many mol of CO2 are formed by the complete reaction of 1.4 mol of

C6H12O6?

An oxide of Nitrogen contains 63.1% Oxygen and has a molar mass of 76.0 g/mol

What is the theoretical yield of sodium chloride formed from the reaction of 2.2g of hydrochloric acid and 3.4g of sodium hydroxide?

For CN^1-+ H₂S —> HCN + HS^1- Justify by the Lewis acid-base definitions why the following reactants behave. Specify the elements involved for each reactant

a) CN^1-

b) H₂S

Equation A: HSO₄ ^-1 (ac)= SO₄^-2 (ac) + H₃O^-1(ac) , Ka = 1.2 x 10^-2

According to the value of Ka to 298k, it is observed that if you increase four times the concentration of products,then the symbol in the chemical equation that demonstrates how that effect could be counteracted would be___________.

justify with two or more sentences

A balloon contains 4 moles of an ideal gas with a volume of 5.0L. If an additional 8 moles of the gas are added at constant pressure and temperature, what will be the final volume of the balloon?
