Question

1 mole ag2co3 is strongly heated then the residue will be of how many moles

Answer 1

Answer:

Ag2CO3—>Ag2O+CO2 is the correct equation

Answer 2

3.5 MOLES OF RESIDUE WILL BE FORMED ON HEATING OF SILVER CARBONATE.

Explanation:

• When a compound is heated it undergoes decomposition reaction.
• In this type of reaction, a specie decompose to form 2 or more products.
• Silver carbonate when heated undergoes endothermic reaction to form silver metal, carbon dioxide, and oxygen.
• The reaction can be written as:

        $2Ag_{2} CO_{3}-->4Ag+2CO_{2}+O_{2}$

• When 2 moles of silver carbonate decompose, 7 moles of residue is formed.
• So, when 1 mole of silver carbonate will decompose, it will for 3.5 moles of residue.

        $Ag_{2} CO_{3}-->2Ag+CO_{2}+\frac{1}{2} O_{2}$
