A clean piece of magnesium ribbon is weighed and then reacted with excess dilute hydrochloric acid to form a magnesium chloride solution. The solution is evaporated to dryness and the solid residue is weighed.

Question Parts

( a )
Write the balanced chemical equation for the reaction between magnesium metal and hydrochloric acid.
( b )
The mass of the magnesium ribbon before the reaction was 0.250 g and the mass of the dried solid residue obtained after evaporation was 0.950 g. Using this data, determine the empirical formula of the chloride formed.
( c )
Based on the empirical formula obtained and the observed properties of the solid (white crystalline solid with high melting point and conducts electricity when molten), discuss the type of chemical bond present in the compound.
