Question

40 grams of calcium reacts with 71 grams of chlorine to produce ________ g of calcium chloride.

Explanation:

Step1: Apply the law of conservation of mass

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. So, the mass of reactants equals the mass of products.

Step2: Calculate the mass of calcium chloride

Mass of reactants = Mass of calcium + Mass of chlorine = \(40\space g+71\space g = 111\space g\)

Answer:

\(111\)
