Answer:
If 0.20 mole of Cl 2 is added to the equilibrium mixture, will the concentration of PCl 5 increase or decrease? If the equilibrium constant for this reaction is expressed in terms of concentrations, written as follows: Here, , and represent the molar concentrations of, , and respectively. Chapter 10, Problem 60CQ is solved.
Step-by-step explanation:
Answer:
4 - 4x³ + 20x² - 20x
Step-by-step explanation:
(g × f)(x) = g(x) × f(x) = (x³ + 5x)(4x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x³(4x - 4) + 5x(4x - 4) ← distribute both parenthesis
= 4 - 4x³ + 20x² - 20x
This can also be done using FOIL, that is
(x³ + 5x)(4x - 4)
= 4 - 4x³ + 20x² - 20x
Answer:
31/99
Step-by-step explanation:
Becuase the numerator is lesser than the denominator
Step-by-step explanation:
sum of internal angles of any triangle = 180 degrees
sum of an exterior angle and an interior angle = 180 degrees
Using the sine ratio, the length of the missing side is: 11.8.
<h3>How to Find Missing Side Using the Sine Ratio?</h3>
The sine ratio is, sin ∅ = opposite/hypotenuse.
Given the following:
∅ = 24°
Opposite = x
Hypotenuse = 29
sin 24 = x/29
x = (sin 24)(29)
x = 11.8
