Acetylene (C2H2) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen(O2) gas, producing carbon dioxide gas and water vapor. Calculate the moles of carbon dioxide produced by the reaction of 0.070 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
