This reaction is... exothermic. Yes, absorbed. Suppose 18.7 g of CH, react. Yes, released. Will any heat be released or absorbed? No. If you said heat will be released or absorbed in the second part of this question, calculate how much heat will be released or absorbed. Round your answer to 3 significant digits.
