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?\no 10 g\no 15 g\no 45 g\no 450 g
Answer
Explanation:
Step1: Apply law of conservation of mass
According to the law of conservation of mass, in a chemical - reaction, the total mass of reactants is equal to the total mass of products.
Step2: Calculate total mass of reactants
The mass of lead oxide is 30 g and the mass of ammonia is 15 g. The total mass of reactants is $30 + 15=45$ g. So, the total mass of products will also be 45 g.
Answer:
45 g
