serious [3.7K]

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>

PLEASE HELP ASAP!!!!! WILL GIVE BRAINLIEST TO FIRST CORRECT ANSWER
Sunny_sXe [5.5K]

Answer:

Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons

Hope that helps!

The following system is at equilibrium:
Delvig [45]

Answer:

1) No shift

2) No shift

3) Leftward shift

4)Rightward sifht

Explanation:

1) 2) Adding N or Removing N in the equilibrium will produce No shift, because of its solid state, the N is not contemplated in the equilibrium equation:

K=\frac{[L]^2}{[M]^3}

3) Increasing the volume produces a decrase in the preassure due to the expansion of the gases. This will cause a leftward shift, because the system will try to increase the moles of gas and in consecuence of this, also increase the preassure.

4) Decreasing the volume has the opposite effect of the item 3): the preassure will increase and the system will consume moles of gas to decrease it, producing a rightward shift.
