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.
A combustion reaction is a major class of chemical reactions. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. In the more general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product.Combustion is an exothermic reaction, so it releases heat, but sometimes the reaction proceeds so slowly that a temperature change is not noticeable.Good signs that you are dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water and heat as products.ombustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water.
