Question

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

Answer 1

Answer:

Y>Q>W>Z>X

Explanation:

Each more reactive element on the list replaces from a compound any of the elements below it (less reactive).

Q>W

Z>X

W>Z

Y>Q

Thus,

Y>Q>W>Z>X

Answer 2

Answer:

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
