1. will hydrazine dissolve in water? why or why not?

Explanation:

Hydrazine ($\ce{N2H4}$) has polar molecules and can form hydrogen bonds with water molecules (since water is polar and has -OH groups, and hydrazine has -NH groups that can participate in H - bonding). The principle "like dissolves like" applies here—polar substances (hydrazine) dissolve in polar solvents (water) due to intermolecular forces like hydrogen bonding and dipole - dipole interactions.

Answer:

Yes, hydrazine will dissolve in water. This is because hydrazine is a polar molecule and can form hydrogen bonds with water molecules. According to the "like dissolves like" principle, polar substances (hydrazine) are soluble in polar solvents (water) as the intermolecular forces (hydrogen bonding, dipole - dipole interactions) between hydrazine and water molecules are favorable for dissolution.
