Question

10. Identify “X', 'y' and 'z' in the following reaction :
2 KCIO, (x) gives to 2 KCl (x) + 0,(z)
(a) x = gas; y = reaction condition, z = gas
(l) x = solid ; y = liquid; z = gas
(c) x = number of moles of KCIO, ; y = reaction condition; z = no. of
molecules of oxygen.
(d) x = physical state of KClo, and KCl; y = reaction condition;
z = physical state of 02.​

Answer 1

Answer:X=solid

Y=liquid

Z=gas

Explanation:

Answer 2

x = Physical state of KClO and KCL, y = reaction condition, z = physical state of 0₂ (Option d)

The reaction is given as:

2KCL0₃ (x) →(y)  2KCL (x) + O₂ (z)

• The above-given reaction is a decomposition reaction as the potassium chlorate(KCL0₃) compound breaks to form potassium chloride(KCL) and oxygen( O₂).
• This reaction is endothermic in nature, heat is given as the source of energy to break the bonds of the compound.
• Since the number of moles of reactants and products are mentioned in front, x and z can not be the number of moles

Hence, the state of the reactants and the products would be:

x = Physical state of KClO and KCL, y = reaction condition, z = physical state of 0₂
