It's a conductor meaning metal is good for radiating heat.
Carboxylic acids and alcohols have higher boiling point
than other hydrocarbons due to their polarity and from the fact that they form
very strong intermolecular hydrogen bonding. This is due to the large
difference in their electronegativity that forms between the oxygen and the
hydrogen atom.

Answer:
7.5×10²³ ions
Explanation:
Given data:
Mass of magnesium sulfate = 75.0 g
Number of ions = ?
Solution:
Number of moles of magnesium sulfate:
Number of moles = mass/molar mass
Number of moles = 75.0 g/ 120.36 g/mol
Number of moles = 0.623 mol
Magnesium sulfate formula: MgSO₄
Number of moles of ions in 1 mole of MgSO₄ = 2 mol (Mg²⁺ and SO₄²⁻)
Number of moles of ion in 0.623 moles of MgSO₄:
2 mole ×0.623 = 1.246 mol
Number of ions:
1 mole contain 6.022×10²³ ions
1.246 mol × 6.022×10²³ ions / 1mol
7.5×10²³ ions
