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 : The correct option is, (c)

Explanation :

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

The given balanced decomposition reaction of barium carbonate is,

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

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
