Write an equation that represents the thermal decomposition of $\text{HCl}$.
Using all relevant bond energy values from the Data Booklet, explain why the thermal stability of $\text{HF}$ is much greater than that of $\text{HCl}$.
Explain what is meant by the term electronegativity, and how it relates to bond polarity.
Draw a ‘dot-and-cross’ diagram to show the bonding in $\text{SF}_4$. Include all outer shell electrons in your diagram.
State whether a molecule of $\text{SF}_4$ has a dipole moment. Explain your answer.
Suggest a reason why sulfur can form both $\text{SF}_4$ and $\text{SF}_6$ whereas oxygen can only form $\text{OF}_2$.
State a major source of atmospheric sulfur dioxide.
State one environmental consequence of atmospheric sulfur dioxide.
