An atom of radium (ra) forms a monatomic ion which of the following ions does it most likely form?

1 answer:

7 0

The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be $[Rn]7s^{2}$

It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.

Therefore, Radium with an electronic configuration of $[Rn]7s^{2}$ will lose the two 7s electrons to form the cation with +2 charge.

A compound has an empirical formula of CHBr2. If it’s molar mass is 345.6 grams, what is it’s molecular formula

djyliett [7]

Answer:

The molecular formula is C2H2Br4

Explanation:

Molar Mass of CHBr2 = 12 + 1 + (2x80) = 12 + 1 + 160 = 173

The molecular formula = n x empirical formula

Molar Mass of the compound = 345.6

Empirical formula = CHBr2

n(CHBr2) = 345.6

n x 173 = 345.6

n = 345.6/173 = 2

Therefore the molecular formula is n(CHBr2) = 2(CHBr2) = C2H2Br4

What is true if a liquid and a gas are in equilibrium?

IRISSAK [1]

Answer:

Recall that, at the boiling point, we observe that both liquid and gas are at equilibrium with one another. This is true at every combination of applied pressure and boiling point temperature. ... The applied pressure will be greater than the vapor pressure, and all of the gas will condense into the liquid
