In a synthesis reaction you start with 1.7L of hydrogen, how many liters of water will be produced

1.7L of water.

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.
