Long-run marginal cost is the slope of the long-run total cost curve. With TC (Q) =2 Q, the slope of the long-run total cost curve is 2, and thus MC (Q) = 2. Long-run mar-ginal cost also does not depend on Q. Its graph is the same horizontal line.This exercise illustrates a general point.ong-run marginal cost is the slope of the long-run total cost curve.

Combustion Definition. Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light. Combustion is considered an exergonic or exothermic chemical reaction. It is also known as burning.

Examples: 2 H 2 + O 2 â 2H 2 O + heat and. CH 4 + 2 O 2 â CO 2 + 2 H 2 O + heat are both combustion reactions.M Images, Getty Images.
