Question

A biology student is learning about the different properties of water and is curious to understand how water is formed. They learn that when hydrogen gas (H2) and oxygen gas (O2) come together, the water molecule (H2O) is formed. What type of reaction is this?

Answer 1

The type of reaction where hydrogen gas (H2) and oxygen gas (O2) come together to form water (H2O) is called a synthesis reaction.

The type of reaction where hydrogen gas (H2) and oxygen gas (O2) come together to form water (H2O) is called a synthesis reaction.

In this type of reaction, two or more substances combine to form a more complex substance.

The general equation for a synthesis reaction is:

Reactant + Reactant → Product

For the reaction between hydrogen gas and oxygen gas to form water, the equation would be:

H2(g) + O2(g) → H2O(l)
