Question

Which of the following shows the balanced equation for the reaction that represents the decomposition of barium carbonate (BaCO3)? (2 points) Select one: a. BaO + CO2yields BaCO3 b. 2BaO + CO2yields 2BaCO3 c. BaCO3yields BaO + CO2 d. 2BaCO3yields 2BaO + CO2

Answer 1

BaCO3 = BaO + CO2, so the answer is C

Answer 2

Answer : The correct option is, (c)
`BaCO_3(s)\rightarrow BaO(s)+CO_2(g)`

Explanation :

Decomposition reaction : It is a type of chemical reaction in which one reactant breaks into two or more smaller compounds.

`AB\rightarrow A+B`

The given balanced decomposition reaction of barium carbonate is,

`BaCO_3(s)\rightarrow BaO(s)+CO_2(g)`

In this reaction, 1 mole of barium carbonate decomposes to yields 1 mole of barium oxide and 1 mole of carbon dioxide.
