Question

Balance the following chemical equation :-

a) Magnesium reacts with dilute hydrochloric

acid.

b) Ferric oxide reacts with aluminium.

c) Silver nitrate reacts with sodium chloride.​

Answer 1

Answer:

A) Mg + HCI =MgCi2 + H2

B) Fe2O3+2Al→AL2O3+2Fe.

C)AgNo3 + NacI = AgCI + NaNo3

Explaintion =

A) When magnesium ribbon reacts with hydrochloric acid, magnesium chloride will be formed and hydrogen gas is liberated. There will be a change in temperature of the test tube, slight fizzing of gas bubbles,then the magnesium ribbon will dissolve into water, leaving in blue.

B) Ferric oxide reacts with aluminium to produce aluminium oxide and iron.

C) Sodium chloride (NaCl) reacts with silver nitrate (AgNO3) to produce silver chloride (AgCl) and sodium nitrate (NaNO3).
