Thirty grams of lead oxide and fifteen grams of ammonia react completely to produce solid lead, nitrogen gas, and liquid water. what will be approximate mass of all three products? 10 g 15 g 45 g 450 g

45 g  Thirty grams of lead oxide and fifteen grams of ammonia react completely to produce solid lead, nitrogen gas, and liquid water.

The approximate mass of three products are 45g.

Explanation:

Law of Conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another. Total mass on the reactant side is always equal to the total mass on the product side.

This law is followed by all the balanced chemical equations.

For the reaction of lead oxide and ammonia, the equation follows:

Total mass on the reactant side = Mass of PbO + Mass of = (30 + 15) = 45 g

As, this is a balanced chemical equation and hence, will follow law of conservation of mass. So,

Total mass of the products = Total mass of the reactants = 45 g

Therefore, the approximate mass of three products are 45g.

they are all solids.
