Question

6. Support with example that compound formation takes place with energy changes using water formation and iron sulphide formation.​

Answer 1

Answer:

Solution:

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

formula:

The burning of methane gas (CH4) in plain air or in presence of oxygen we get:

(CH)+O+CO+HO

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

NaHS+ NaOH → Na2S + H2O

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