Question

N2H4 (I)--> N2 (g) + 2 H2(g)
2 H2(g) + O2 (g) --> 2 H20 (I)
- If you lost some of your hydrogen gas during your reaction and only produced 7.25 g of H2
(g) how many grams of water will you produce?


Question 2

1g = 1ml and 1 L = 1000 ml

How many liters of water will this produce?
-
Watney needs 618 L of water to survive on Mars until the next mission arrives and can
rescue him. Does 7.25g of H2 produce enough water for him to survive?

Answer 1

Answer:

65.25 grams of water

Explanation:

Moles of H2 = mass/ M.w

= 7.25g /2

=3.625 mol H2

Moles of H2O = moles of H2 = 3.625 mole

Mass of H2O = mol * molar wight

= 3.625 * 18 = 65.25 g H2O
