Following are three possible reactions that could occur when a sample of KClO3 (s) is heated. One goal of this lab is to determine the correct one. Balance all three reactions. a. ___ KClO3 (s) ___ KClO2 (s) + O2 (g) b. ___ KClO3 (s) ___ KClO (s) + O2 (g)
c. ___ KClO3 (s) ___ KCl (s) + O2 (g)

2KClO3 (s)  → 2KCl (s) + 3O2 (g)  (option C)

Explanation:

Step 1:

a. ___ KClO3 (s) → ___ KClO2 (s) + O2 (g)

On the left side we have 3x O (in KClO3) and on the right side we have 4x O (2x in KClO2 and 2x in O2). To balance the amount of O on both sides, we have multiply KClO3 and KClO2 by 2.

2KClO3 (s) → 2KClO2 (s) + O2 (g)

This is not the reaction that occurs when KClO3 is heated

b. ___ KClO3 (s) ___ KClO (s) + O2 (g)

This equation is already balanced

KClO3 (s) → KClO (s) + O2 (g)

c. ___ KClO3 (s) ___ KCl (s) + O2 (g)

On the left side we have 3x O (in KClO3) and on the right side we have 2x O (in O2). To balance the amount of O on both sides, we have multiply KClO3 by 2 and O2 by 3.

On the left side we have 2x K (in 2KClO3) and on the right side we have 1x K (in  KCl). To balance the amount of K on both sides, we have multiply KCl on the right side by 2.

2KClO3 (s)  → 2KCl (s) + 3O2 (g)

When KClO3 is heated strongly, it breaks down, releasing oxygen gas and leaving behind a thermally stable (i.e., heat-insensitive) solid residue of an ionic potassium compound, as KCl

Option C is the correct answer

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
