Potassium chloride is an electrovalent compound, while hydrogen chloride is a covalent compound. But, both conducts electricity in their aqueous solutions. Explain.

Draw the electron dot structure of covalent compound methane (non-polar) and HCl (polar) and give two difference between them.

For each compound mentioned above give the formulae of ions formed in aqueous solution.

An element M burns in oxygen to form an ionic bond MO. Write the formula of the compounds formed if this element is made to combine with chlorine and sulphur separately.
