Consider the following data for five hypothetical elements: Q, W, X, Y, and Z. Rank the elements from most reactive to least reactive. Combination Observation of reaction Q+W+ Reaction occurs X+Z+ No reaction W+Z+ Reaction occurs Q++Y Reaction occurs

Y > Q > W > Z > X

Explanation:

Reactivity series gives information on the reactive nature of element. Only more reactive element will replace a less reactive element in it compound. More reactive element usually displace less reactive element in it compound.

From the reaction above Y displace element Q from it compound. Element Q displace W from it compound.  W displace Z in it compound. The element X cannot displace Z from it compound because it is less reactive .Their is no reaction.

Base on the reactivity element  Y is the most reactive.

Y > Q > W > Z > X

it's filtration, but this is an assumption so my apologies if i got this

i'm pretty sure it is letter c.) car
