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.
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.
The correct answer is "There are two atoms of hydrogen and one atom of oxygen in a water molecule."
To understand why twice as much hydrogen as oxygen is formed in the decomposition of water, we need to examine the chemical formula of water (H2O). Water consists of two hydrogen atoms (H) bonded to one oxygen atom (O).
During the decomposition of water, a chemical reaction occurs that breaks the bonds between hydrogen and oxygen atoms. This reaction can be represented as 2H2O → 2H2 + O2.
According to the balanced chemical equation, two molecules of water decompose to form two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2).
Therefore, twice as much hydrogen gas is formed compared to oxygen gas because each water molecule produces two hydrogen atoms but only one oxygen atom.
