The following do not represent valid ground-state electron configurations for an atom either because they violate the Pauli excl
svetoff [14.1K]

Answer:

<em>For both cases the answer is C</em>

Explanation:  

We can see that the orbitals are not filled in the order of increasing energy and the Pauli exclusion principle is violated because it does not follow the correct order of the electron configuration; In the first exercise after the 2s2 orbital, the 2p2 orbital follows.

For the second exercise, you must start in order with level 1 and correctly filling each of the sublevels corresponding to each level until reaching level 7 and thus completing the desired number of electrons.

Which metal atoms can form ionic bonds by losing electrons from both the outermost and next to outermost principal energy levels
RoseWind [281]

Full question options;

(Fe, Pb, Mg, or Ca)

Answer:

Iron - Fe

Explanation:

We understand tht metals pretty much form bonds by losing their valence (outermost electrons). But this question specifically asks for metals that lose beyond their outermost electrons; next to outermost principal energy levels.

Pb, Mg, and Ca only lose their outermost electrons to form the following ions;

Pb2+, Mg2+, and Ca2+.

This is because their ions have achieved a stable octet configuration - the dreamland of atoms where they are satisfied and don't need to go into reactions again.

Iron on the other hand has the following electronic configurations;

Fe:  [Ar]4s2 3d6

Fe2+:  [Ar]4s0 3d6

Fe3+:  [Ar]4s0 3d5

This means ion can lose both the ooutermost electrons (4s) and next to outermost principal energy levels (3d). So correct option is Iron.

A student titrates a solution containing 0.050 moles of calcium hydroxide with phosphoric acid. How many moles of phosphoric aci
lina2011 [118]

Answer:

The answer to your question is 0.33 moles of H₃PO₄

Explanation:

Data

moles of Ca(OH)₂ = 0.050

moles of H₃PO₄ = ?

Process

1.- Write the balanced chemical equation

           3Ca(OH)₂  +  2H₃PO₄    ⇒   Ca₃(PO₄)₂   +   6H₂O

             Reactants        Elements       Products

                    3                      Ca                     3

                   12                       H                     12

                   14                      O                      14

2.- Calculate the moles of phosphoric acid

      3 moles of calcium hydroxide --------------- 2 moles of phosphoric acid

      0.5 moles of calcium hydroxide -----------   x

      x = (0.5 x 2)/3

      x = 0.33 moles
