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

What happened to the concentration of the product of H2O when the reaction shifts to the left
lilavasa [31]

I might need a diagram for this, but I have a vague idea of what you are talking about.

If H20 is going left it means the temperature is going lower.

The molecules will condense to slowly become ice

Which gas sample at STP has the same number
Flauer [41]

<span>STP signifies standard temperature and pressure. This conditions are at 1 atmospheric pressure and 0 degrees Celsius. It has been said that at these conditions, one mole of a gas molecule is equivalent to 22.4 liters of volume. Therefore, the correct answer is the second option which is 2 L of CH4.</span>
