Answer:
13 moles of KClO₃ will decompose to gives 13 moles of KCl.
Explanation:
Given data:
Moles of potassium chloride = 13.0 mol
Moles of KClO₃ = ?
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
Now we will compare the moles of KCl with KClO₃.
KCl : KClO₃
2 : 2
13 : 13
So 13 moles of KClO₃ will decompose to gives 13 moles of KCl.

Explanation:
Answer:
D, E and F
Explanation:
About tetrachloro cobalt complexes, the following facts have been observed
- Color of the tetrachloro cobalt complexes is blue.
- They do not decompose on heating that means synthesis of tetra chloro is endothermic.
About hexa aqua cobalt complexes, the following facts have been observed
- Color of the hexa aqua cobalt complexes is pink color.
- They decompose on heating and remain stable on cooling that means process of synthesis of hexa aqua cobalt complexes is exothermic.
Based on above, the correct statements are:
The correct is chloro cobalt complex is blue and aqua cobalt
complex is pink.
The chloro complex is favored by heating.
If the chloro complex is a product, then the reaction must be endothermic.
The correct options are D, E and F.
