How much sulphur dioxide is produced on complete combustion of 1 kg of coal containing 6.23percent sulphur?

Approximately , assuming that all sulfur in that coal was converted to .

Explanation:

Look up the relative atomic mass of and on a modern periodic table:

Convert the unit of the mass of coal to grams:

.

Mass of sulfur in that much coal:

.

The relative atomic mass of sulfur is . Therefore, the mass of each mole of sulfur atoms would be . Calculate the number of moles of atoms in that of sulfur:

.

Each molecule contains one sulfur atom. Therefore, assuming that all those (approximately) of sulfur atoms were converted to molecules through the reaction with , (approximately) of molecules would be produced.

Calculate the mass of one mole of molecules:

.

The mass of that of molecules would be:

.

a

explanation:

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
