Question

1.5g of hydrogen react with oxygen to form water.calculate the amount of water produced in this reaction?​

Answer 1

Answer :

4.5 g of Water would be formed

Given :

1.5 grams of Dihydrogen reacts with Oxygen to form Water

Explanation :

We have to find the Amount Of Water produced by the end of the reaction.

The reaction will be represented as :

$\tt H_2 + O_2 \longrightarrow H_2O$

Balancing the Equation,

$\tt 2H_2 + O_2 \longrightarrow 2H_2O$

Here,

2 moles of Hydrogen forms 2 moles of Water

➠ 1 moles of Hydrogen would form 1 mole of Water

➠ 2g of Hydrogen forms 18g of Water

Now,

Let the Amount Of Water formed by 1.5 g of Hydrogen be x

$\sf \: 2g \: of \: H_2 \longrightarrow 18g \: of \: H_2O \\ \\ \sf \: 1.5 \: g \: of \: H_2 \longrightarrow \: x \: grams \: of \: H_2O$

Thus,

$\sf \: 2x = 1.5 \times 18 \\ \\ \leadsto \: \sf \: x = 1.5 \times 9 \\ \\ \leadsto \: \boxed{ \boxed{ \sf x = 4.5 \: g}}$
