Answer:

B) k_{sp} =[Mg_{aq} ]*[OH_{aq}]^{2}

Explanation:

Ksp is the solubility product constant.

For a generic chemical equation

AB_{2} = A_{aq}+2B_{aq}

The Ksp for this generic chemical equation is

k_{sp} =[A_{aq} ]*[B_{aq}]^{2}

So the Ksp fot the Mg(OH)2 is

k_{sp} =[Mg_{aq} ]*[OH_{aq}]^{2}

What subatomic particle is responsible for combining the atoms together to form a new substance?
Tanya [424]
The answer to this question would be: electron

When atoms bind together, that mean they shared at least one electron. The electron is located on the outer side of the atoms so the electron from an atom can collide with other electrons from another atom. The protons and neutron can't make bind because it was in the middle of the atom and won't collide each other.

4. To how much water should 50 mL of 12 M hydrochloric acid be added to
Novosadov [1.4K]

Answer : The volume of water added are, 15 mL

Explanation :

Formula used :

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the initial molarity and volume of HCl.

M_2\text{ and }V_2 are the final molarity and volume of water.

We are given:

M_1=12M\\V_1=50mL\\M_2=40M\\V_2=?

Putting values in above equation, we get:

12M\times 50mL=40M\times V_2\\\\V_2=15mL

Hence, the volume of water added are, 15 mL
