Determine the enthalpy for the reaction A+B --> C If we know the following: A+E --> C+D; delta H = -200 kJ
D+B --> E; delta H = -100 kJ

Explanation:

here is the answer to the question

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
