<h2>Answer:</h2>

A) the enthalpy of fusion

Explanation:

the heat of vaporization, is the amount of energy needed to change a liquid to a gas at constant temperature and pressure. The energy required to melt a solid to a liquid is called the <u><em>heat of fusion</em></u>,  and the heat of sublimation is the energy.

What is the oxidation state of co in [co(oh2)6]2?
Ahat [919]

Correct compound is [Co(H2O)6]^+3

The oxidation state of Co is +3

[Co(H2O)6]^+3

Let

 Co be x

 H2O = 0

 x + (0)6 = 3

 x = 3

What is oxidation state?

The oxidation state, commonly known as the oxidation number, is the potential charge that an atom would have if all of its bonds to other atoms were fully ionic. It describes the degree of atom oxidation within a chemical compound.The oxidation state may be positive, negative, or zero in theory.

The oxidation number, sometimes referred to as the oxidation state, is the total number of electrons that an atom gains or loses while uniting with another atom to form a chemical bond.

Which one of the following is a balanced equation?
ziro4ka [17]

Answer: OA is a balanced equation.

Explanation: For an equation to be balanced, the number of atoms and the total charge of each element in the reaction, of the product and reactant side must be the same.

Considering OA; 6 atoms of nitrogen is present in the reactant side. Shifting to the product side, 6 atoms of nitrogen is also present. Taking the other element in the reaction into account, the number of atoms of each element balances on both sides.

A mysterious compoud with the chemical formula MX (Ksp 1.27x10-36) is present in two different solutions. What is its molar solu
qwelly [4]

<u>Answer:</u> The molar solubility of MX is 2.54\times 10^{-36}M

<u>Explanation:</u>

We are given:

K_{sp}(MX)=1.27\times 10^{-36}

The chemical equation for the ionization of MX follows:

MX\rightleftharpoons M^+(aq.)+X^-(aq.)

                  S         S

The expression of K_{sp} for above equation is:

K_{sp}=S\times S      ......(1)

The chemical equation for the ionization of M_2SO_4 follows:

M_2SO_4\rightleftharpoons 2M^+(aq.)+SO_4^{2-}(aq.)

 0.25M           0.5M      0.25M

Total concentration of cation from both the equation is:

[M^+]=0.5+S

As, K_{sp}(MX), so S is also very very less than 1 and can be easily neglected.

So, [M^+]=0.5M

Putting values in equation 1, we get:

1.27\times 10^{-36}=0.5\times S\\\\S=2.54\times 10^{-36}M

Hence, the molar solubility of MX is 2.54\times 10^{-36}M
