How do you determine if and ion has a<br> noble-gasconfiguration?
Soloha48 [4]

Explanation:

Noble gas configuration is defined as the configuration which contains completely filled orbitals.

For example, oxygen atom when gain two electrons then it forms oxygen ion (O^{2-}).

Atomic number of oxygen atom is 8 and so, its number of electrons will also be 8. But when it gain two electrons then it has total 10 electrons. Hence, electronic configuration of O^{2-} is as follows.

          1s^{2}2s^{2}2p^{6}

Since, there are completely filled orbitals in an O^{2-} ions. Therefore, it means this ion has a  noble-gas configuration.

Thus, we can conclude that any specie which shows completely filled orbitals will have noble-gas configuration.

What is the mass of 0.2 moles of ethanol​
Verdich [7]

Answer:

<u>Answer</u><u> </u><u>is</u><u> </u><u>9</u><u>.</u><u>2</u><u> </u><u>grams</u>

Explanation:

Molar mass of ethanol

{ \bf{CH _{3}CH_{2}OH}} = (12 \times 2) + (6 \times 1) + (16) \\  = 46 \: g

for moles:

{ \sf{1 \: mole \: of \: ethanol \: weighs \: 46 \: g}} \\ { \sf{0.2 \: moles \: weigh \: (0.2 \times 46) \: g}} \\  = 9.2 \: g
