<h3>Question:</h3>
what type of precipitation occurs more frequently during a winter storm?
Answer:
snow and sleet
Explanation:
- freezing air temperatures near the ground and up to the clouds will cause precipitation to fall as either snow or ice.

Gold has 79 protons on the periodic table
Answer:
1.33 Å
Explanation:
Given that the edge length , a of the KCl which forms the FCC lattice = 6.28 Å
Also,
For the FCC lattice in which the anion-cation contact along the cell edge , the ratio of the radius of the cation to that of anion is 0.731.
Thus,
.................1
Also, the sum of the radius of the cation and the anion in FCC is equal to half of the edge length.
Thus,
...................2
Given that:
To find,
Using 1 and 2 , we get:
<u>Size of the potassium ion = 1.33 Å</u>
