Answer:
a. Sn or Si ⇒ Sn
b. Br or Ga ⇒ Ga
c. Sn or Bi ⇒ similar in size
d. Se or Sn ⇒ Sn
Explanation:
The larger atom has a larger atomic radius. We have to consider how varies the atomic radius for chemical elements in the Periodic Table. In a group (column), the atomic radius increases from top to bottom while in a period (file), it increases from right to left.
a. Sn or Si ⇒ Sn
They are in the <u>same group</u>. Sn is on the top, so it has a larger atomic radius.
b. Br or Ga ⇒ Ga
They are in the <u>same period</u>. Ga is located at the left so it has a larger atomic radius.
c. Sn or Bi ⇒ similar
They are not in the same group neither the same period. Bi is located more at the bottom, so it would be larger than Sn, but Bi is also at the right side, so it would be smaller than Bi. Thus, they have comparable sizes.
d. Se or Sn⇒ Sn
They are not in the same group neither the same period. Se is located at the top and right side compared to Sn, so Sn is the larger atom.

The second one is: 1.692atm
Hope this helps!
Explanation: Look at Photo Attached
One example could be scanners linked to a networked database. Those little hand scanners that you see at a Publix or Wal-Mart report back to series of systems that allow stores to track inventory across the entire business allowing them to anticipate when they should order more of one item or see what has been selling particularly well -- or not. Consumers don't see any of that when they buy their Count Chocula, but the database systems do and those can be extremely complex. I hope this helps you out!! have a wonerful day!!
The answer is B=1
-2(3b-2)=8b-10
-6b+4=8b-10
-14b+4=-10
-14b=-14
B=1
Answer: stronger
Explanation:
the attractive forces in a solid tend to be stronger_ than in the liquid state, for the liquid state it tends to be weaker
