Which of the following illustrates the conservation of matter? A. SnO2 + H2 --> Sn + 2 H2O B. 2 C + O2 --> CO2 C. KOH + HB
olga2289 [7]

C. KOH + HBr → KBr + H₂O

Explanation:

The two equations above illustrates the conservation of matter. The law of conservation of matters states that

               "in a chemical reaction, matter is neither created nor destroyed but transformed from one form to another".

By this law, we understand that the amount of a particular matter we are starting with should be the one we end with.

    KOH + HBr → KBr + H₂O

Conserving                          Product                          Reactants

     K                                         1                                           1

     O                                         1                                           1

      H                                         2                                          2

We can see that the amount on both sides are the same.
