A homogeneous mixture is formed when it is dissolved in water
Sergeeva-Olga [200]3 years ago
4 0

Answer is: homogeneous mixture.

Salt (NaCl) and water make a homogeneous mixture (the same proportions of its components throughout any given sample), because both substances are polar.

Solution is homogeneous mixture composed of two or more substances.  

In aqueous solution, solvent is water and solute (in this example sodium chloride) is a substance dissolved in water.

Homogeneous solution of salt and water can be separated with heating (evaporating the water).

Using the following combustion reaction, describe how it follows the laws of conservation of mass and energy. CH 4 +2O 2 CO 2 +2
AURORKA [14]

Answer:

Explanation:

The law of conservation of mass states that "mass in a system remains constant and that the mass of the product is remains the same as that of the reactants".

Law of conservation of energy states that "energy is neither created nor destroyed in the course of chemical or physical change but can be transformed from one form to another".

 Let us properly write the equation:

               CH₄ + 2O₂ → CO₂ + 2H₂O

For the conservation of mass:

  C has 1mole on both sides

   H has 4mole on both sides

   O has 4 mole on both sides

For energy, during combustion process, the methane CH₄ burns to liberate heat energy. This is an energy conversion process in which chemical energy in methane releases heat energy.

Find the pHpH of a solution prepared from 1.0 LL of a 0.15 MM solution of Ba(OH)2Ba(OH)2 and excess Zn(OH)2(s)Zn(OH)2(s). The Ks
charle [14.2K]

Answer:

pH  = 13.09

Explanation:

Zn(OH)2 --> Zn+2 + 2OH-   Ksp = 3X10^-15

Zn+2 + 4OH-   --> Zn(OH)4-2   Kf = 2X10^15

K = Ksp X Kf

  = 3*2*10^-15 * 10^15

  = 6

Concentration of OH⁻ = 2[Ba(OH)₂] = 2 * 0.15 = 3 M

                Zn(OH)₂ + 2OH⁻(aq)  --> Zn(OH)₄²⁻(aq)

Initial:           0             0.3                      0

Change:                      -2x                     +x

Equilibrium:               0.3 - 2x                 x

K = Zn(OH)₄²⁻/[OH⁻]²

6 = x/(0.3 - 2x)²  

6 = x/(0.3 -2x)(0.3 -2x)

6(0.09 -1.2x + 4x²) = x

0.54 - 7.2x + 24x² = x

24x² - 8.2x + 0.54 = 0

Upon solving as quadratic equation, we obtain;

x = 0.089

Therefore,

Concentration of (OH⁻) = 0.3 - 2x

                                    = 0.3 -(2*0.089)

                                  = 0.122

pOH = -log[OH⁻]

         = -log 0.122

          = 0.91

pH = 14-0.91

     = 13.09
