Answer:
She will need 7 tanks of gas. It will cost $273.
Step-by-step explanation:
First, we divide the amount of miles that she needs to go by the amount she can drive on one tank.
2240/320 = 7
She will need 7 tanks. Multiply the cost of one tank by 7.
$39*7 = $273
It will cost $273 total.
The correct equilibrium constant expression for this equation is;

Given
Consider the equation below.

<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;

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