Examine the equation.

Chemistry
1 answer:
Alisiya [41]3 years ago
5 0

Explanation:

The reaction expression is given as;

                 2H₂_{g}   +  O₂_{g}   →   2H₂O_{l}

From the balance reaction expression:

 2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;

This produces 2 mole of water on the product side of the expression.

The product is in liquid form.

 This reaction is a synthesis reaction because a single product is formed from two reactants.

speed in air < speed in water.
wavelength in air < wavelength in water.
The variation is direct.
