Answer:
The maximum mass of carbon dioxide that could be produced by the chemical reaction is 70.6gCO_{2}
Explanation:
1. Write down the balanced chemical reaction:

2. Find the limiting reagent:
- First calculate the number of moles of hexane and oxygen with the mass given by the problem.
For the hexane:

For the oxygen:

- Then divide the number of moles between the stoichiometric coefficient:
For the hexane:

For the oxygen:

- As the fraction for the oxygen is the smallest, the oxygen is the limiting reagent.
3. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction:
The calculations must be done with the limiting reagent, that is the oxygen.

852 x 40.0= 4260 x v2
<span>v2= 8 L </span>
<span>b) 852 x 40 = p2 x 69.0 </span>
<span>p2= 494 torr</span>
Ba! It is a metal and wants to lose 2 electrons ASAP
The maximum amount of silver will be all of that contained in the solution.
Silver in solution:
Solution volume = 4,700 ml
Solution mass = 1.01 x 4,700
Solution mass = 5170 g
Amount of silver = 5,170 x 0.032
Amount of silver = 165.44 grams
