Question

calculate the volume of hydrogen that will combine with 40 litres of oxygen to form steam at 150°C and atmospheric pressure​

Answer 1

The volume of oxygen gas is {eq}40\ L {/eq}.

The balanced chemical equation for this reaction is given as follows.

{eq}2H_2(g)+O_2(g)\rightarrow 2H_2O(g) {/eq}

From balanced chemical equation, {eq}1 {/eq} unit volume of oxygen gas combines with {eq}2 {/eq} unit volume of hydrogen gas.

So, {eq}40\ L {/eq} of oxygen gas will combine with {eq}2\times 40=80\ L {/eq} of hydrogen gas.

Therefore, the volume of hydrogen gas combine with oxygen is 80 L.
