Question

which of these elements is found in both carbohydrates and water? helium nitrogen carbon oxygen

Explanation:

• Carbohydrates have the general formula \(C_x(H_2O)_y\), so they contain carbon (\(C\)), hydrogen (\(H\)), and oxygen (\(O\)).
• Water has the formula \(H_2O\), so it contains hydrogen (\(H\)) and oxygen (\(O\)).
• Helium (\(He\)) is a noble gas and not present in either.
• Nitrogen (\(N\)) is not in water or most simple carbohydrates.
• Carbon (\(C\)) is not in water.

Answer:

Oxygen
