Question

When burning magnesium is placed in a gas jar of carbon dioxide, it continues to burn and a black solid 1s produced.
(i) How could you show that the gas jar contains carbon dioxide?
(ii) Suggest what the black solid 1s.
(iii) What is the name of the other product of the reaction.

Answer 1

Explanation:

Burning mg in co2 forms mgo that is magnesium Oxide

Burning mg in co2 forms mgo that is magnesium Oxide It burns in air to produce Oxide

Burning mg in co2 forms mgo that is magnesium Oxide It burns in air to produce Oxidemg burns in the presence of co2 because the,oxygen in the CO2 is able to bond with mg and produced an Oxide

it forms powdery product that is mgo

Answer 2

2 Mg + CO2 → 2 MgO + C

Explanation:

When burning magnesium is placed in a glass jar containing carbon dioxide, it will continue to burn and a black solid is produced.

Magnesium burns in presence of carbon dioxide because, the oxygen in the carbon dioxide is able to bond with magnesium and produce a magnesium oxide. Carbon is formed as a biproduct. The carbon which is formed is in the form of soot.

2 Mg + CO2 → 2 MgO + C
