In the decomposition of water, why is twice as much hydrogen as oxygen formed?(1 point)

Hydrogen gas has two atoms, and oxygen gas has one atom.

Some oxygen gas escapes the reaction, and hydrogen gas is conserved.

There are two atoms of hydrogen and one atom of oxygen in a water molecule.

Hydrogen atoms are twice the size of oxygen atoms.

There are two atoms of hydrogen and one atom of oxygen in a water molecule.

The correct answer is: There are two atoms of hydrogen and one atom of oxygen in a water molecule.

The correct answer is: There are two atoms of hydrogen and one atom of oxygen in a water molecule.

To understand why there is twice as much hydrogen gas as oxygen gas formed during the decomposition of water, we need to look at the chemical composition of water. A water molecule is made up of two hydrogen atoms bonded to one oxygen atom. This means that when water decomposes, it breaks down into its constituent elements: hydrogen and oxygen.

The decomposition of water can be represented by the following equation:

2H2O --> 2H2 + O2

In this equation, the two water molecules (H2O) on the left side are decomposed into two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2).

Since each water molecule contains two hydrogen atoms and one oxygen atom, when the water molecules are decomposed, the resulting hydrogen gas and oxygen gas will also be in a ratio of 2:1. This means that for every two molecules of hydrogen gas formed, only one molecule of oxygen gas is formed.

Therefore, the correct answer is that there are two atoms of hydrogen and one atom of oxygen in a water molecule, which is why twice as much hydrogen as oxygen is formed during the decomposition of water.
