I would say it should be 7 because the functions should be
f(x) = 3 - x
f(-4) = 3 - (-4) = 7

Even on my Wolfram it says 7

What is the correct equilibrium constant expression for this equation? 2 upper C upper o upper F subscript 2 (g) double arrow up
Alekssandra [29.7K]

The correct equilibrium constant expression for this equation is;

\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}

Given

Consider the equation below.

\rm {2COF_2(g)}\rightleftharpoons C0_2(g)+CF_4(g)

<h3>What are Species?</h3>

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

<h3>Equilibrium constant expression;</h3>

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;

\rm K_{eq}=\dfrac{(C0_2)(CF_4)}{(COF_2)^2}

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

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

Help me to do this please
Tanzania [10]

If x represents the mass of 1 ball in kg, then the balance shows ...

... 6x = x + 9 kg

... 5x = 9 kg

Then 6x is ...

... (6/5)·5x = (6/5)·9 kg = 10.8 kg

0.8 kg = 0.8·1000 g = 800 g

so 10.8 kg is ...

... D. 10 kg 800 g

If sec 2A = 1/sin 13A, determine the angle A in degrees.
kupik [55]
Sec 2 A = 1 / cos 2 A
1 / cos 2 A = 1 / sin 13 A
cos 2 A = sin 13 A
2 A = 90° - 13 A
2 A + 13 A = 90°
15 A = 90°
A = 90° : 15
Answer:
B ) A = 6°
