Both chlorides are covalent and have low melting points. In terms of the attraction between particles, suggest why these chlorides melt at low temperatures.
Chloride P, S$_2$Cl$_2$, is formed when sulfur reacts with chlorine. Write the symbol equation for this reaction.
Complete the dot-and-cross diagram in Fig. 3.1 for a molecule of chloride Q, SCl$_2$. Show only outer electrons.
Suggest two condition changes that would lead to a lower concentration of chloride Q at equilibrium.
Define the term activation energy.
Give the symbol for activation energy.
Complete Table 3.1 to show the effect, if any, when the conditions are changed. Use only the words increases, decreases or no change.
Explain, using oxidation numbers, why: • sulfur is oxidised in the forward reaction • chlorine is oxidised in the reverse reaction.
