If  O2(g) reacts with H2(g) to produce  H2O, what is the volume of H2O obtained from 1 L of O2?
joja [24]

Answer:

2L

Explanation:

We'll begin by writing the balanced equation for the reaction this is illustrated below:

2H2 + O2 —> 2H2O

1 mole of a gas occupy 22.4L.

1 mole of O2 occupy 22.4L.

2 moles of H2O occupy = 2 x 22.4 = 44.8L.

From the balanced equation above,

22.4L of O2 produced 44.8L of H2O.

Therefore, 1L of O2 will produce = 44.8/22.4 = 2L.

Therefore, 1L of O2 will produce 2L of H2O.

Why do farmers spray water over their crops before a frost?
Nezavi [6.7K]

Answer:

When water freezes and turns into ice, it releases latent heat. Then, the ice that builds up on the plant will insulate it from the colder surrounding air temperatures. Because of this, some growers choose to spray their crop with water before the freeze occurs.
