Describe the arrangement of particles in a ceramic material.
State the property of a ceramic material that makes it suitable for use as supports beneath overhead power cables.
Describe the structure and bonding in the chloride produced when aluminium reacts with chlorine. Suggest how this accounts for the low sublimation temperature.
Calculate the empirical formula of the chloride. Show your working.
A $1.36\,\text{g}$ sample of this chloride occupied a volume of $200\,\text{cm}^3$ at $200\,^{\circ}\text{C}$ and $100\,\text{kPa}$. Calculate the relative molecular mass, $M_r$, of the chloride. Give your answer to three significant figures.
Deduce the molecular formula of the chloride at $200\,^{\circ}\text{C}$.
