Homework Answers
A.
H2 gas will be evolved. Any metal on reacting with acids will produce hydrogen gas.
B.
Zn + 2HCl -----> ZnCl 2 + H2
C.
Decomposition of Hydrogen peroxide yields oxygen gas.
The smoldering toothpick will start burn strongly.
D.
Mn + 2H2O2 = MnO2 + 2H2O
E.
In presence of flame both burns vigorously.
But H2 flame will have a bluish color but Oxygen flame have different color based on what is burning. Here toothpick it will be a light yellow colour.

Part IV. Decomposition Into a test tube, place about 2 mL of 3% hydrogen peroxide along with a pea size amount of Mnog Manganese dioxide, the common name, is used as a catalyst. Remember, that a catalyst is used to lower the activation energy of a reaction, thereby speeding up the reaction. It does not get con- sumed in the reaction and therefore is not part of your balanced chemical equation. It is written above the reaction arrow in a...
