Sodium and water react according to the following equation. if 51.5 g of sodium are added to access water, how many liters of hydrogen gas are formed the stp ? show all work. 2na+2h2o—> 2naoh+h2

Answer is: volume is 25.08 liters.

Balanced chemical reaction: 2Na + 2H₂O → 2NaOH + H₂(g).

m(Na) = 51.5 g; mass of sodium.

n(Na) = m(Na) ÷ M(Na).

n(Na) = 51.5 g ÷ 23 g/mol.

n(Na) = 2.24 mol; amount of sodium.

From chemical reaction: n(Na) : n(H₂) = 2 : 1.

n(H₂) = 2.24 mol ÷ 2.

m(H₂) = 1.12 mol; amount of hydrogen gas.

V(H₂) = n(H₂) · Vm.

V(H₂) = 1.12 mol · 22.4 L/mol.

V(H₂) = 25.08 L; volume of hydrogen gas.

u i forgot the answer?

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
