Hydrogen Peroxide

H2 gas

Zinc

Explanation:

1) Hydrogen Peroxide (H2O2) is a colourless liquid and a very powerful oxidising agent.

2) Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals.

3) Granulated zinc reacts with most acids to release Hydrogen gas. Granulated zinc gives more surface area for the acid to act, so hydrogen is formed faster. Also, granulated zinc has copper as an impurity, which catalyses the reaction.

Two identical metallic spheres, having unequal, opposite charges are placed at a distance 0.90m apart in air. After bringing them in contact with each other,they are again placed at the same distance apart. Now the force of repulsion between them is 0.025 N. Calculate the final charge on each of them.
