You multiply the percentage and theoretical yield together.
Answer: m Most likely Group2 metals and Group 17 non-ktta
Explanation:
A little more information is needed to be certain, but the likely answer is that X belongs to Group 2 and Y belongs to Group 17. Group 2 metals (Be, Mg, Ca, Sr, Ba, etc.) are all divalent. They gave rive up 2 electrons each to return to a full shell. Group 17 elements (e,g, F, Cl, Br, I, etc.) all require 1 electron to reach a full valence shell. That would make the proportion 1X to 2Y, or XY2. It is possible that a metal outside of Group 2 would also have a valency of 2. Iron(II) forms FeCl2, for example.
Stoichiometry measures the quantitative relationships, and is used to determine the amounts of products and reactants that are produced or needed in a given reaction
Answer:
The obvious difference between substitution and elimination reactions is that substitution reactions replace one substituent with another while elimination reactions simply remove the substituent. ... The major difference between the groups is the number of steps the reaction takes place over.
substitution and elimination can be seenis by looking at the bond or the H+ . When substitution occurs, the H+ will be subtituted with other atom. As for elimination, when this reaction occur which mostly involve alkane, new bondwill appear.
