The solubity product constant (Ksp) is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. The more soluble a substance is, the highe the Ksp value it has. Ksp is determined for a system when equlibrium is established and when the two phase system is saturated.

If chlorine (nonmetal) has seven valence electrons while barium (metal) has

swat32

Answer: Two chlorine atoms

Explanation:

Chlorine is a nonmetal belonging to group 7 of the periodic table. It has an atomic number of 17 distributed as (2, 8, 7), so it has 7 valence electrons and needs JUST ONE to complete its outermost shell.

Cl + e- ---> Cl-

On the other hand, barium is a metal belonging to group 2 on the periodic table. It has an atomic number of 56 with 2

valence electrons in its outermost shell, and gives off the two electrons to form a stable octet structure.

Ba ----> Ba2+ + 2e-

Thus, barium loses its 2 outermost electrons to form a Ba2+ ion, while TWO chlorine atoms receive them to form 2Cl- resulting in an ionic bond in the compound, BaCl2 (Barium Chloride)

Ba2+ + 2Cl- ---> BaCl2

A 3.540-g sample of an unknown metal M is burned in the presence of excess oxygen, producing the oxide M2O3(s) and liberating 18

pshichka [43]

Answer:

a) Sm

Explanation:

Hello,

This substantiation could be done by knowing how to compute the released energy for 1 mol the oxide. Thus, for Sm, the computation turns out into:

$Q=-1823.0\frac{kJ}{mol}*\frac{1molSm_2O_3}{348.72gSm_2O_3} *3.540gSm_2O_3\\Q=-18.5kJ$

The sign just indicates that the heat is released due to the chemical reaction and it matches with the indicated heat in the statement.

Best regards.

What is the highest sublevel for the element Boron?

Nesterboy [21]

Answer:

Explanation:

Boron is a member of group 13. The highest energy sub-level is usually found on the outermost shell of the atom of the element involved.

For a group 13 element, its outermost shell configuration is ns2 np1. The electronic configuration for boron is; 1s2 2s2 2p1.

Hence the highest energy sub-level in boron is 2p.
