Question

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.

    Answer:

    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

    Zn + CuSO_4 --> ZnSO_4 + Cu

    so here we have

    Zn = 10.1 g

    CuSO_4 = 18.6 g

    ZnSO_4 = 20 g

    Cu = 8.7 g

    Now total mass of reactant is given as

    M_1 = 10.1 + 18.6 = 28.7 g

    Mass of the product is given as

    M_2 = 20 + 8.7 = 28.7 g

    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
