19 multiple choice 1 point a student mixes 4 grams of hydrogen with 32 grams of oxygen to form water. what is the total mass of water produced? 32 grams 16 grams 36 grams 28 grams
Answer
Explanation:
Step1: Apply law of conservation of mass
In a chemical reaction, the total mass of reactants equals the total mass of products.
Step2: Calculate total mass of reactants
The mass of hydrogen is 4 grams and the mass of oxygen is 32 grams. The total mass of reactants is $4 + 32=36$ grams. So the mass of water (product) is also 36 grams.
Answer:
36 grams
