Carbohydrates are needed as part of a balanced diet. Which formula shows glucose? Tick one box only. C_(6)H_(12)O_(6) CO_(2) H_(2)O O_(2)

## Step 1: The general formula for carbohydrates is \( Cx(H2O)y \). This means that a carbohydrate molecule is basically a bunch of different structural arrangements of carbon molecules with a pair of hydrogen and oxygen for each atom of carbon in the carbohydrate. All carbohydrates have the general formula of carbon rings or chains and the hydrogen and oxygen ratio is 2:1 just like water (H2O).## Step 2: Comparing the options , , , with the formula of carbohydrates, only represents the ratio taken as six atoms of Carbon, is taken as twelve atom of Hydrogen and indicates 6 atoms of Oxygen.## Step 3: The carbohydrate in this case is glucose which has this formula .
