A sample of 5.0 g of hydrogen gas reacts with 5.0 g of oxygen gas. 2H2 (g) + O2 (g) → 2H2O(l)

a. What is the theoretical yield of water?

b. What is the limiting reactant?

c. What is the excess reactant?

d. How much excess reactant remains?

e. If 4.2 g of water is actually produced, what is the percent yield?

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.
