A neutral atom with the electron configuration 2-8-6 would most likely form a bond with an atom having the configuration
Fittoniya [83]

Answer:

The configuration of the atom would be 2-8-2.

Explanation:

Any atom of an element combines with other element to complete its octet and become stable.

The electron configuration of the given atom is 2-8-6. That means the atom has 6 electrons in its outermost shell. To become stable the atom should have 8 electrons in its outermost shell. The given atom has 6 electrons so it either lose 6 electrons or gain 2 electrons to complete its octet.

But we know the atom having 5,6,7 electrons in its outermost shell they do not lose, they gain either 3 or 2 or 1 electrons to complete its octet.

So we say that atom with the electron configuration 2-8-6 bond with the atom having electron configuration 2-8-2.

You have just started working at a swimming pool supply store and they have nitric acid on their shelves. In order to help custo
Tanzania [10]

Answer:

The concentration of hydronium ions is 0.0155 mol/L

Explanation:

The aqueous solution ionization reaction for nitric acid is as follows;

HNO₃ + H₂O → NO₃⁻ + H₃O⁺

Whereby HNO₃ is a strong acid and it undergoes complete ionization in an aqueous solution

Hence one mole of HNO₃ produces one mole of H₃O⁺ ions

0.0155 mol/L HNO₃ will have 0.0155 moles of H₃O⁺ in one liter of the solution

The concentration of hydronium ions = 0.0155 mol/L.

Infer if the mineral Talc would be a good choice when building a statue outside?
ruslelena [56]
Talc is not a good choice when building a statue because the mineral Talc is one of the weakest minerals on the Mohs Scale with a hardness of 1 since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down.

1. How many molecules of NO3 are there in 12 moles of NO3?
9966 [12]

Answer:

7.22*10^24 molecules

Explanation:

Since one mole has 6.02*10^23 you'd multiply that number by 12

that equals 7.224*10^24 but you need sig figs
