Answer:

1. K = [CF2Cl2] [HCl]^2 / [CCl4] [HF]^2

2. K = [NH3] [HCl] / [NH4Cl]

3. K = [H2SO4] / [SO3] [H2O]

Explanation:

The equilibrium constant for a chemical reaction is simply the ratio of the concentration of the products to that of the reactants

The equilibrium constant for the reactions are written below.

1. CCl4(g) + 2HF(g) ⇌ CF2Cl2(g) + 2HCl(g)

K = [CF2Cl2] [HCl]^2 / [CCl4] [HF]^2

2. NH4Cl(s) ⇌ NH3(g) + HCl(g)

K = [NH3] [HCl] / [NH4Cl]

3. SO3(g) + H2O(1) ⇌ H2SO4(1)

K = [H2SO4] / [SO3] [H2O]

Answer:

4. K = [CF₂Cl₂] [HCl]² / [HF]² [CCl₄]

5. K = [NH₃] [HCl]

6. K = 1 / [SO₃]

Explanation:

Equilibrium constant expressions are defined as the ratio between concentrations of products and concentrations of reactants powered to its reaction quotient (Compounds in solid or liquid phase are not taken in the expression).

For the reactions:

4. CCl₄(g) + 2HF(g) ⇌ CF₂Cl₂(g) + 2HCl(g)

Equilibrium expression, K, is:

5. NH₄Cl(s) ⇌ NH₃(g) + HCl(g)

6. SO₃(g) + H₂O(l) ⇌ H₂SO₄(l)

Thermohaline circulation _______. a. supplies heat to polar regions b. causes salt lake formation c. causes oxbow lake formation

DerKrebs [107]

Thermohaline circulation that occur in the ocean part that flows across sea surface help to supply heat to polar regions.

<h3>What is Thermohaline circulation?</h3>

The thermohaline circulation refer to a section and region of the ocean circulation which is majorly driven by heat gradient and freshwater that flows across the sea surface and also from the mixture of heat and salt that occur at the inside part of the ocean.

Therefore, Thermohaline circulation help to supply heat to polar regions.

Calculate the hight of a column of liquid glycerol in meters required to exert the same pressure as 3.02 m if CCl4?

katovenus [111]

Answer:

Approximately $3.81\; \rm m$ .

Explanation:

Look up the density $\rho$ of carbon tetrachloride, $\rm CCl_4$ , and glycerol:

Density of carbon tetrachloride: approximately $1.59\times 10^{3}\; \rm kg \cdot m^{-3}$ .
Density of glycerol: approximately $1.26\times 10^{3}\; \rm kg \cdot m^{-3}$ .

Let $g$ denote the gravitational field strength. (Typically $g \approx 9.81\; \rm N \cdot kg^{-1}$ near the surface of the earth.) For a column of liquid with a height of $h$ , if the density of the liquid is $\rho$ , the pressure at the bottom of the column would be:

$P = \rho\cdot g \cdot h$ .

The pressure at the bottom of this carbon tetrachloride column would be:

$\begin{aligned} P &= \rho \cdot g \cdot h \\ & \approx 1.59\times 10^{3} \; \rm kg \cdot m^{-3} \times 9.81\; \rm N \cdot kg^{-1} \times 3.02 \; \rm m \approx 4.71 \times 10^{4} \; \rm N \cdot m^{-2} \end{aligned}$ .

Rearrange the equation $P = \rho\cdot g \cdot h$ for $h$ :

$\displaystyle h = \frac{P}{\rho \cdot g}$ .

Apply this equation to calculate the height of the liquid glycerol column:

$\begin{aligned}h &= \frac{P}{\rho \cdot g} \\ &\approx \frac{4.71 \times 10^{4}\; \rm N \cdot m^{-2}}{1.26 \times 10^{3}\; \rm kg \cdot m^{-3} \times 9.81\; \rm N \cdot kg^{-1}} \approx 3.81\; \rm m\end{aligned}$ .
