Rank the ions in each set in order of decreasing size, and explain your ranking:
iragen [17]

Ranking of the ions in each set in order of decreasing size -

Cs+ > Ba²⁺ > Sr²⁺

Cs+ has the biggest size, because its more downward (compared to Sr2+) and more to the left (compared) ot Ba2+.

Sr2+ has the smallest size because it's more upwords (compared to Cs+ and Ba2+).

For isoelectronic ions, the greater the nuclear charge , the greater is the attraction for electrons and smaller is ionic radius. In other words, size of the isoelectronic ions decreases with increase in atomic number.

Cl3+ has the smallest ion among all.

Look at sample problem 18.15 in the 8th ed Silberberg book. Identify the Lewis acids and Lewis bases in the following reactions:
Lelechka [254]

Answer:

1. H+ + OH- <--------> H2O

H+ is a Lewis acid

OH- is a Lewis base

2. Cl- + BCl3 <---------> BCl4-

Cl- is a Lewis base

BCl3 is a Lewis acid

3. K+ + 6H2O <------> K(H2O)6+

K+ is a Lewis acid

H2O is a Lewis base

Explanation:

By definition, Lewis acid is an electron pair acceptor while a Lewis base is an electron pair donor.

Potassium ion accept electron pairs from 6 water molecules which donate the electron pairs.

What does the atomic mass describe?
harkovskaia [24]
B., the mass of the nucleus of the atom.
Both the protons and the neutrons are inside the nucleus. The atomic number of an atom is the number of protons, and if you subtract the atomic number from the atomic mass you can find the number of neutrons an atom has. 
So, the mass of the protons plus the mass of the neutrons, which are both inside the nucleus, equals the atomic mass.

How many atoms are there in 0.57 mol of Zn
AfilCa [17]

Answer:

3.43 * 10^23 atoms of zinc

Explanation:

According to Avogadro's law, one mole of a substance contains a certain number of atoms of the substance commonly referred to as the Avogadro's number.

We already know from Avogadro's law that;

1 mole of zinc contains 6.02 * 10^23 atoms of zinc

Therefore;

0.57 mole of zinc will contain 0.57 * 6.02 * 10^23/1

which gives us 3.43 * 10^23 atoms of zinc
