Answer #1
  1. Sodium carbonate is ionic solid. It dissociate into ions on dissolving in water. Due to movement of free ions the solution become good conductor of electricity.

Methanol is covalent compound. It do not dissociate in water, so it is not good conductor of electricity.

2. Methanol and methane both are covalent compounds. Methanol has intermolecular hydrogen bonding due to this it becomes water soluble.

Dear student, please send multiple questions separate as we have time limit to answer.

    Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
