Answer:
1.7L of water.
Step-by-step explanation:
Given parameters:
Volume of hydrogen gas = 1.7L
Unknown:
Volume of water produced = ?
Solution:
A synthesis reaction is one in which two compounds or molecules combines together to give a product or products.
Synthesis of water from hydrogen gas is represented by the equation below:
2H₂ + O₂ → 2H₂O
We clearly see that;
2 mole of hydrogen gas gives 2 mole of water as the product;
From Gay-lussac's law of combining volume "when gases react, they do so in volumes which bear a simple ratio to one another and to the volume of the product if gaseous, temperature and pressure remaining constant".
2H₂ + O₂ → 2H₂O
2 volumes of hydrogen gas will produce 2 volumes of water
1.7L of hydrogen gas will also produce ; 1.7L of water.
