The correct equilibrium constant expression for this equation is;

[tex]\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}[/tex]

Given

Consider the equation below.

[tex]\rm {2COF_2(g)}\rightleftharpoons C0_2(g)+CF_4(g)[/tex]

In an equilibrium constant expression, you do not include the solid substances; only gases and dissolved substances.

It is the quotient of the product of the concentrations of the species on the right-hand side of the equilibrium equation, each raised to its corresponding coefficient, and the product of the concentrations of the species on the left-hand side, each raised to its corresponding coefficient.

Therefore,

The correct equilibrium constant expression for this equation is;

[tex]\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}[/tex]

Hence, the correct equilibrium constant expression for this equation is;

[tex]\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}[/tex].

Answer:

10 units

Step-by-step explanation:

To find the distance between two points on a graph, we use the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2[/tex] where [tex]d[/tex] is the distance between points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].

For this problem, we will identify [tex](x_1,y_1)\rightarrow(5,7)[/tex] and [tex](x_2,y_2)\rightarrow(11,-1)[/tex]:

[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(-1-7)^2+(11-5)^2}\\\\d=\sqrt{(-8)^2+(6)^2}\\\\d=\sqrt{64+36}\\\\d=\sqrt{100}\\\\d=10[/tex]

Therefore, the distance between [tex](5,7)[/tex] and [tex](11,-1)[/tex] is 10 units

Answer:

see explanation

Step-by-step explanation:

The slope m of the line = tan45° = 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1 , then

y = x + c

To find c substitute (2, 1 ) into the equation

1 = 2 + c ⇒ c = 1 - 2 = - 1

y = x - 1 ← equation of line

When x = 0 then y = 0 - 1 = - 1

The line passes through (0, - 1 )

Answer:

Answer:

x=1 and y=7

Step-by-step explanation:

7x−2y=−7;y=7

Rewrite equations:

y=7;7x−2y=−7

Step: Solve y = 7 for y:

y=7

Steps: Substitute 7 for y in 7x−2y=−7:

7x−2y=−7

7x+(−2)(7)=−7

7x−14=−7 (Simplify both sides of the equation)

7x−14+14=−7+14 (Add 14 to both sides)

7x=7

7x/7 = 7/7 (Divide both sides by 7)

x = 1

So the answer is, x=1 and y=7

Answer:100

Step-by-step explanation:

The mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

Given that weigh of the person is 50 KG. The mass of the sodium chloride in one person is given below.

[tex]1 \;\rm Person = 2\times 10^2\;\rm g[/tex]

The mass of sodium chloride is calculated as given below.

[tex]1.8\times 10^3 \;\rm Person = 2\times 10^2 \times 1.8\times 10^3[/tex]

[tex]1.8\times 10^3 \;\rm Person = 3.6\times 10^5\;\rm g[/tex]

Hence we can conclude that the mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

Answer:

3 is less then then it's..

7x n -3

The answer is (7 x n) - 3

The product of 7 and a number means 7 x n and 3 less than it means -3.

Answer:

x ≤ 2

Step-by-step explanation:

                                       -6x - 7 ≥ -19

Add 7 to both sides:            -6x ≥ -12

Divide both sides by 6:          -x ≥ -2

Divide both sides by -1:            x ≤ 2

When you divide by a negative, you have to switch the sign around (hence why I chose to do this in separate steps, so it's clearer)

Acute Triangle

Step-by-step explanation:

All angles are less than 90 degrees.

Answer:

20 degrees

Step-by-step explanation:

I don't know why the 30 degrees was given at point A because you don't need that.

The equation is;

Sinx=  Opposite/Hypotneuse

     x = Sin inverse (50/146)

        = 20.02

        Rounded to 20 degrees

The measure of the angle x or the value of x is 20 degrees after applying the sin ratio in a right-angle triangle DCB.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a right-angle triangle shown in the picture.

From the right angle triangle we can find the value of x or measure of the angle x by applying the trigonometric ratios:

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying sin ratio in a right-angle triangle DCB:

sinx = 50/146

sinx = 0.342

x = 20.02 ≈ 20 degrees

Thus, the measure of the angle x or the value of x is 20 degrees after applying the sin ratio in a right-angle triangle DCB.

Step-by-step explanation:

3(t+5) = 9

3t+15 = 9

3t = -6

t = -2

2(f-7) = -10

2f - 14 = -10

2f = 4

f = 2

-(c - 9) = 4

-c + 9 = 4

-c = -5

c = 5

-6(2t + 8) = -84

-12t - 48 = -84

-12t = -36

12t = 36

t = 3

-10 (s + 2) = -57

-10s - 20 = -57

-10s = -37

s = 3.7

7(3w + 8)/3 = -9

By cross multiplication,

7(3w + 8) = -27

21w + 56 = -27

21w = -83

w = -3.95

35/5 = (F - 32)/9

7 = (F - 32)/9

By cross multiplication,

63 = F - 32

63 + 32 = F

95 = F
