Acetylene (C₂H₂) is commonly prepared by the reaction of calcium carbide (CaC₂) with water to form acetylene and calcium hydroxide (Ca(OH)₂). Calculate the mass (in g) of acetylene that can be prepared by the reaction of 6.4 g CaC₂ with 10.5 g H₂O.

The mixture of A₂B and B₂ before it reacts to form AB₃ is illustrated in the image below. What is the limiting reactant? How much AB₃ is formed?

When 3.2 mol of C₇H₈, 3.2 mol of C₆H₁₄, and 3.2 mol of CH₃(CH₂)₃COOH are reacted with oxygen and undergo complete combustion, determine the compound that produces the least number of moles of H₂O.

The following image shows a mixture of nitrogen and oxygen gases at room temperature. When the temperature of the mixture is raised, nitric oxide (NO) and nitrogen dioxide (NO₂) are produced.

2 N₂ + 3 O₂ → 2 NO + 2 NO₂

What will be the number of molecules of each substance present in the mixture when the reaction is complete.

Given the following reaction below: 

4A + 3B + 6C →D

Identify the limiting reactant if 7 moles of A react with 2 moles of B and 3 moles of C

Rubidium metal reacts with iodine gas as described in the following equation:

2Rb(s) + I₂(g) → 2RbI(s)

Initially, the reaction mixture contains 45.2 g Rb and 92.3 g I₂. How many grams of the excess reactant remain after the reaction has occurred completely?

Limestone (CaCO₃) reacts with hydrochloric acid according to the equation CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂. If 1.00 mol of CO₂ has a volume of 22.4 L under the reaction conditions, how many liters of gas can be formed by reaction of 2.35 g of CaCO₃ with 2.35 g of HCl? Which reactant is limiting?
