Answer: 27\times 10^{23}

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

1 mole of Hg contains = 6.023\times 10^{23} atoms of mercury

Thus 4.5 moles of Hg contains = \frac{6.023\times 10^{23}}{1}\times 4.5=27.099\times 10^{23} atoms of mercury

Thus the number of atoms in 4.5 moles of mercury are 27\times 10^{23} atoms of mercury.

Answer:

D. 27.099 x 10²³.

Explanation:

  • It is known that every 1.0 mole of an atom contains Avogadro's no. (6.022 x 10²³) atoms.

<em>So, 4.5 mol of Hg will contain:</em>

(4.5 mol)(6.022 x 10²³) = 27.099 x 10²³ atoms.

<em>So, the right choice is: D. 27.099 x 10²³.</em>

Jill then wrote the formulas for all the possible compounds that sodium can form with the other ions. What formulas did she writ
sp2606 [1]

Explanation:

Sodium has atomic number of 11 and its electronic configuration is given by:

[Na]=1s^22s^22p^63s^1

The nearest stable electronic configuration to sodium is of the neon. So, in order to attain stability of noble gas it will loose its single electron.

Na\rightarrow Na^++1e^-

[Na^+]=1s^22s^22p^63s^0

Sodium has single valency that is 1.

Let nbe the valency of the ion 'X'

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Na_nX_1

So, the formulas for all the possible compounds that sodium can form with the other ions will be:

Na_nX_1
