 The vertical sequence of the layers of soil is called a soil ____?
Bad White [126]
Soil profile
Soil profile is the vertical sequence of the layers of soil. Furthermore, there are actually six layers of the soil which involves the organic matter, -where most humus is present-, surface soil, the subsoil, the parent rock, and the bedrock as the innermost and core layer of the soil. In addition each soil layer has three to four soil horizon. These horizons are the physical features of the soil, mainly the texture, color and composition.

If a student has 125 mL of a 4.00 M CuSO4 solution and needs a 1.50 M solution, what volume do they need to dilute it to?
lara31 [8.8K]

Answer:

333.3mL

Explanation:

Using the formula as follows:

C1V1 = C2V2

Where;

C1 = initial concentration (M)

C2 = final concentration (M)

V1 = initial volume (mL)

V2 = final volume (mL)

According to the information provided in this question,

C1 = 4.00M

C2 = 1.50M

V1 = 125mL

V2 = ?

Using C1V1 = C2V2

4 × 125 = 1.5 × V2

500 = 1.5V2

V2 = 500/1.5

V2 = 333.3mL

Therefore, the CuSO4 solution needs to be diluted to 333.3mL to make 1.50 M solution.

Consider the following system at equilibrium where H° = 16.1 kJ, and Kc = 6.50×10-3, at 298 K. 2NOBr(g) 2NO(g) + Br2(g)If the VO
Norma-Jean [14]

Answer:

1) The value of Kc : (C.) remains the same

2) The value of Qc : (A.) is greater than Kc

3) The reaction must : (B.) run in the reverse direction to reestablish equilibrium.

4) The number of moles of Br2 will : (B.) decrease

Explanation:

Value of concentration equilibrium constant Kc depends only on temperature. Since temperature remains constant, therefore, Kc remains constant.  Decrease in volume means increase in pressure. Increase in pressure favors the side with less gaseous species.  Hence, increase in pressure will favor the reverse reaction towards reactants.
