2Li + H2SO4=Li2SO4 + H2 How many liters of hydrogen gas, H2 at STP can be produced from 3.0 moles of Li? The molar volume of a g
Gemiola [76]

Answer:

volume of H_2=33.6 litre

Explanation:

Firstly balance the given chemical equation,

2Li + H_2SO_4=Li_2SO_4 + H_2

From the given balance equation it is clearly that,

2 mole of Li gives  1 mole of H2 gas

2 mole Li⇔1 mole H_2

1 mole Li⇔0.5 mole H_2

3 mole Li⇔1.5 mole H_2

hence

3 mole of Li will give 1.5 mole H2 gas

therefore volume of gas produced from 3 mole Li at STP = 1.5\times22.4 \frac{L}{mol}

volume of H2=33.6 litre

Why do we need to have common denominators when adding fractions?
jeyben [28]
So that we have the right answer once we do the addition
Say that I measure my self at 12 feet with one measuring stick, and go on with another measuring stick that tells me I'm 3 meters tall, if I added those, I would be at something like 15/46 or something like that. See that would be wrong. We would want the right denominator so that it could be easier and also correct.
