Question 41 – Predicting chemical reactions - Questions

The table shows the results of the displacement reactions between four metals ( $P$ , $Q$ , $R$ , and $S$ ) and their metal oxides.

Key: $✓\checkmark$ = reaction, $×\times$ = no reaction

	Metal $P\,$ oxide	Metal $Q\,$ oxide	Metal $R\,$ oxide	Metal $S\,$ oxide
Metal $P$	—	$✓\checkmark$	$×\times$	$✓\checkmark$
Metal $Q$	$×\times$	—	$×\times$	$×\times$
Metal $R$	$✓\checkmark$	$✓\checkmark$	—	$✓\checkmark$
Metal $S$	$×\times$	$✓\checkmark$	$×\times$	—

What is the correct order of reactivity of the metals, from most reactive to least reactive?
