Question

support with examples that compound formation takes place with energy changes, using water formation and sulphide formation with chemical reaction s​

Answer 1

Answer:

yes up course

Explanation:

because formation of ozone during course of evolution is from the lighting which is source of energy

Answer 2

Solution:

The chemical reaction for water formation to show energy exchange we use the formula:

The burning of methane gas $\left(C H_{4}\right)$ in plain air or in presence of oxygen we get:

$\left(C H_{4}\right)+O_{2} \rightarrow C O_{2}+H_{2} O$

As methane burns in air it forms carbon dioxide and water

The chemical reaction for sulphide formation to show energy exchange we use the formula:

Sulphide is usually attached with sodium or Hydrogen the formation or the chemical reaction for the sulphide is

$\mathrm{NaHS}+\mathrm{NaOH} \rightarrow \mathrm{Na} 2 \mathrm{S}+\mathrm{H2O}$

The formation of sodium sulphide is formed by sodium hydrosulphur and sodium hydroxide. Boiling off the sodium sulphide we get the conjugate sulphide.
