If m represents an element in group 2 the formula of its chloride would be

MCl₂

Explanation:

Elements in Group 2 of the periodic table are alkaline earth metals and they have 2 electrons in their valence shell. To follow the octet rule, they tend to lose 2 electrons, forming cations M²⁺. Chloride is an anion of formula Cl⁻. For a compound to be electrically neutral, it requires 1 atom of M²⁺ and 2 atoms of Cl⁻ so that the total charge is zero: +2 + 2.(-1) = 0. The resulting formula is MCl₂

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
