Questions: This question has multiple parts. Work all the parts to get the most points. Figure out what is wrong with the following molecular formula and write the correct formula: (Enter the elements in the order they appear in the wrong formula.) a N 2 H 4 (hydrazine) Correct formula: (b) C 4 H 10 (butane) Correct formula:

Correcting the molecular formula for N₂H₄ (hydrazine)

Understanding the given formula

The given formula is \( \text{N}_2\text{H}_4 \), which is the correct molecular formula for hydrazine. Hydrazine is composed of two nitrogen atoms and four hydrogen atoms.

Verifying the formula

Upon verification, \( \text{N}_2\text{H}_4 \) is indeed the correct molecular formula for hydrazine. There is no error in the given formula.

\(\boxed{\text{N}_2\text{H}_4}\)

Correcting the molecular formula for C₄H₁₀ (butane)

Understanding the given formula

The given formula is \( \text{C}_4\text{H}_{10} \), which is the correct molecular formula for butane. Butane is composed of four carbon atoms and ten hydrogen atoms.

Verifying the formula

Upon verification, \( \text{C}_4\text{H}_{10} \) is indeed the correct molecular formula for butane. There is no error in the given formula.

\(\boxed{\text{C}_4\text{H}_{10}}\)

\(\boxed{\text{N}_2\text{H}_4}\)\(\boxed{\text{C}_4\text{H}_{10}}\)
