Students have asked these similar questions
A student wants to determine the melting point of water as part of an investigation into the strength of electrostatic forces. The student considers determining the freezing point of water instead. Is this a valid option?
O No, it is not because the freezing point is not related to electrostatic forces.
O No, it is not because the freezing point is not related to the melting point.
O Yes, it is; and determining the freezing point is likely to be more accurate.
O Yes, it is; but determining the freezing point is likely to be more difficult.

- he following demonstration takes place in a two-step process: rst, solid calcium carbide (CaC2j)reacts with liquid water to produce acetylene gas (C2H2)and aqueous calcium hydroxide.
