A. Heat is released, so the reaction is <u>exothermic</u>.
B. Heat is absorbed, so the reaction is <u>endothermic</u>.

Answer:
11.9 moles of carbon-dioxide will produced.
Explanation:
Given moles of ethane = 5.95 mol
According to reaction 2 moles of ethane produces 4 moles of carbon-dioxide.
Then, 5.95 moles of ethane will produce:
of carbon-dioxide
11.9 moles of carbon-dioxide will produced.
