What is the mass of the single product that is formed from the complete reaction of 2.5 g hydrogen with 7.5 g oxygen?

Question

Quizplus · Accepted Answer

The mass of the product formed from the reaction of hydrogen and oxygen can be determined by the law of conservation of mass, which states that matter is neither created nor destroyed in a chemical reaction. Therefore, the mass of the products equals the mass of the reactants. The total mass of the reactants is 2.5 g (hydrogen) + 7.5 g (oxygen) = 10.0 g. Hence, the mass of the single product, water, formed from the complete reaction is 10.0 g.
