Shay reacts solid zinc and aqueous copper sulfate to form aqueous zinc sulfate and solid copper. If he reacts 10.1 grams of zinc with 18.6 grams of copper sulfate and yields 20 grams of zinc sulfate and 8.7 grams of copper, then was mass conserved? explain how you know.

Now since mass of reactant is equal to mass of the product after the reaction so we can say that mass conservation is applicable here

Explanation:

As we know that zinc reacts with copper sulfate

so the reaction is given as

so here we have

Now total mass of reactant is given as

Mass of the product is given as

Now since mass of reactant is equal to mass of the product after the reaction so we can say that mass conservation is applicable here

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
