Consider the balanced equation. cap n sub 2 cap h sub 4 plus 2 cap h sub 2 cap o sub 2 ce bond right arrow cap n sub 2 plus 4 cap h sub 2 cap o What are the mole ratios of hydrazine open paren cap n sub 2 cap h sub 4 close paren to hydrogen peroxide open paren cap h sub 2 cap o sub 2 close paren and hydrazine to water?

In the balanced equation, the coefficients give the mole ratios. One mole of hydrazine (N₂H₄) reacts with 2 moles of hydrogen peroxide (H₂O₂), so their ratio is 1:2. It produces 4 moles of water (H₂O) per mole of hydrazine, giving a ratio of 1:4. Therefore, the correct choice is D: 1:2 and 1:4.
