(a) Interpretation: The formula and name of the compound that is formed by the reaction of titanium and chlorine at 300°C needs to be determined. It contains 25.25% of Ti by mass. The molecular formula and empirical formula are assumed to be same for the compound. Concept introduction: The group 7A elements show variation from non-metals to metals down in the group. The first element of the group 7A is fluorine with 7 valence electrons. These elements forms halide with metals and exist in X-1 ionic state.
