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?

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

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
