Please help I’ll mark brainliest. Thank you :)
Jobisdone [24]

Answer:

a. There are only 5 electrons in 2p. 2p should be filled with 6 electrons prior to 3s and 3p

b. There are 8 electrons in 2p. 2p should be filled only with 6 electrons (not 8)

Explanation:

The typical electron configuration: 1s2 2s2 2p6 3s2 3p6

a. There are only 5 electrons in 2p

=> should be 1s2 2s2 2p6 3s2 3p2

b. There are 8 electrons in 2p

=> should be 1s2 2s2 2p6 3s2 3p1

What is the volume of water needed to prepare 5000 ml of 0.1 M HCL from a stock solution of4 M
Karo-lina-s [1.5K]

Hey There :

Volume initial = ?

Volume final = 5000 mL

Molarity initial = 4 M

Molarity final = 0.1 M

Therefore :

Mi * Vi = Mf * Vf

4 * vi = 0.1 * 5000

4 vi = 500

Vi = 500 / 4

Vi = 125 mL

Answer A

Hope this helps!

How many milliliters of 0.200 M NH4OH are needed to react with 12.0 mL of 0.550 M FeCl3?
trapecia [35]

Answer:

9.9 ml of 0.200M NH₄OH(aq)

Explanation:

3NH₄OH(Iaq) + FeCl₃(aq) => NH₄Cl(aq) + Fe(OH)₃(s)

?ml of 0.200M NH₄OH(aq) reacts completely with  12ml of 0.550M FeCl₃(aq)

1 x Molarity NH₄OH x Volume Am-OH Solution(L) = 2 x Molarity FeCl₃ x Volume FeCl₃ Solution

1(0.200M)(Vol Am-OH Soln) = 3(0.550M)(0.012L)

=> Vol Am-OH Soln = 3(0.550M)(0.012L)/1(0.200M) = 0.0099 Liter = 9.9 milliliters
