Question

suppose four atoms of oxygen gas and two atoms of hydrogen gas are combined. Determine how many atoms of water and oxygen gas will be produced.

Answer 1

8 oxygen and 2 water molecules

Answer 2

1 Water; 3 free oxygen

Step-by-step explanation:

Since the water molecule (H₂O) consists of two hydrogen atoms and one oxygen atom.

By combining four oxygen gas atoms to two hydrogen gas atoms, as described in the question, covalent bonding between the two hydrogen atoms with one oxygen will occur, leaving three free oxygen atoms for further reactions.

The reaction that forms water molecules can be described as follows:

2H₂ + O₂ = 2H₂O
