Answer:
KCl
Explanation:
Look at the electronegativity differences between the pairs of elements:
KCl: 3.16 - 0.82 = 2.34
BeCl: 3.16 - 1.57 = 1.59
LiCl: 3.16 - 0.98 = 2.18
ClO: 3.44 - 3.16 = 0.28
KCl has the highest electronegativity difference; thus it is the most ionic bond of the 4.

Answer:
the mas is .291 g
Explanation:
the mass of a object does not change. so when added the substance the beaker. you had the mass of both objects together. you know the mass of the beaker and you know the mass of both. since mass does not change. the beakers mass is still 74.605g. the mass of both objects is 74.896. all you have to do is subtract the mass of the beaker from the total mass. 74.896 - 74.605 equals .291g. so the mass of the unknown substance Is .291g
