In the reaction Zn H 2SO 4→ ZNSO4 + H2, which, if any element is oxidized
Sedbober [7]

Answer:

I hope this answer is correct

Explanation:

This is an oxidation-reduction (redox) reaction:

Zn0 - 2 e- → ZnII (oxidation)

2 HI + 2 e- → 2 H0 (reduction)

Zn is a reducing agent, H2SO4 is an oxidizing agent.

<u>Explanation:</u>

Cooking food involves in two types of energies. <em>They are chemical energy and thermal energy. </em>

We use gas for a gas stove.Here gas is chemical energy.when we light the stove the fire lits up and here the <em>chemical energy energy is converted into thermal energy.</em>

Breaking and combining of bonds during combustion gives heat and light.This thermal energy heats the vessels and cooks the food through the <em>process of conduction, convection and radiation. </em>
