Question

which statements correctly describe the relationship between oxygen, hydrogen, and water? select all that apply. water contains two covalent bonds, but a single hydrogen atom has no covalent bonds. water is an atom found in hydrogen and oxygen molecules. hydrogen is one type of atom found in a water molecule. one oxygen atom can covalently bond to two hydrogen atoms to form a water molecule.

Explanation:

• First statement:
• In a water molecule (\(H_2O\)), there are two \(O - H\) covalent bonds. A single hydrogen atom (\(H\)) has no bonds as it is just an atom. This statement is correct.
• Second statement:
• Water (\(H_2O\)) is a molecule, not an atom. Hydrogen (\(H_2\)) and oxygen (\(O_2\)) are also molecules. So, this statement is incorrect.
• Third statement:
• A water molecule (\(H_2O\)) is composed of two hydrogen atoms (\(H\)) and one oxygen atom (\(O\)). So, hydrogen is one type of atom in a water molecule. This statement is correct.
• Fourth statement:
• In a water molecule (\(H_2O\)), one oxygen atom covalently bonds to two hydrogen atoms. This statement is correct.

Answer:

• First statement: Water contains two covalent bonds, but a single hydrogen atom has no covalent bonds.
• Third statement: Hydrogen is one type of atom found in a water molecule.
• Fourth statement: One oxygen atom can covalently bond to two hydrogen atoms to form a water molecule.
