Chapter 5, Problem 73P

Using the balanced equation for the combustion of acetylene, answer the following questions.

   $\begin{array}{l}\text{2H-C}\equiv {\text{C-H + 5O}}_{\text{2}}\to {\text{4CO}}_{\text{2}}{\text{ + 2H}}_{\text{2}}\text{O}\\ \text{ acetylene}\end{array}$

a. How many moles of ${\text{O}}_{\text{2}}$ are needed to react completely with 5.00 mol of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\text{?}$

b. How many moles of ${\text{CO}}_{\text{2}}$ are formed from 6.0 mol of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\text{?}$

c. How many moles of ${\text{H}}_{\text{2}}\text{O}$ are formed from 0.50 mol of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\text{?}$

d. How many moles of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$ are needed to from 0.80 mol of ${\text{CO}}_{\text{2}}\text{?}$
