what would be the mass of the product on the right side of the arrow? 10g 40g
Answer
Explanation:
Step1: Apply law of mass - conservation
In a chemical reaction, the total mass of reactants equals the total mass of products.
Step2: Calculate total mass of reactants
The mass of one reactant is 10g and the other is 30g. So, the total mass of reactants is $10 + 30=40$g.
Answer:
40g
