If you use 10 g of CuSO4 and excess NH3, what is the theoretical yield of Cu(NH3)4SO4?

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.

explanation:

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
