Use the observations in the table to work out which sample is $\text{Ba(OH)}_2$, $\text{NaCl}$, $\text{P}_4\text{O}_{10}$ and $\text{SiCl}_4$. Enter your responses in the table.
(a(ii))[1]
Identify the formula of the white solid produced when sample T reacts with water.
(a(iii))[1]
Name the solution produced when sample U reacts with water.
(b(i))[1]

(b(ii))[1]
Give the formula of another Period 3 oxide that behaves like a ceramic material.
(c)[3]
Tungsten oxide, $\text{W}_x\text{O}_y$, is used to colour ceramic materials. A sample of $\text{W}_x\text{O}_y$ has $79.29\%$ tungsten by mass. Calculate the empirical formula of $\text{W}_x\text{O}_y$. Show your working.
