you need 100.00 ml of h20 and 5.00 ml of
liquid plant food to make a solution for your
plants. you forgot to bring a measuring cup
out to the greenhouse, but you do have a scale
and know that the density of h2o is 1.00
g/cm", the density of liquid plant food is 1.21
g/cm' and 1 cm° = 1 ml. how much of the
liquid plant food would you use?

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
