Based on a kc value of 0.200 and the given data table, what are the equilibrium concentrations of xy, x, and y, respectively?

1 answer:

3 0

There is no given data table but based on the question, the reaction is
xy <=> x + y
If we let M as the initial concentration of xy and c as the in the concentration after the dissociation, then we can use the ICE method
xy <=> x + y
I M
C -c c c
-----------------------------
E M-c c c

Solve for c using
Kc = c(c) / (M - c)
And the concentration of the xy, x, and y can then be determined

If each point in the diagram can act as an endpoint, how many distinct line segments can be formed using the set of points

sdas [7]

Answer:

Option D 6 is the answer.

Step-by-step explanation:

the given points are A, D, C and B. If each point in the diagram can act as end points, we have to calculate number of distinct line segments formed.

This ca be calculated in two ways.

(1) We will form the line segments

AB, AC, AD, BC, BD, DC

Therefore 6 segments can be formed.

(2) By combination method

Number of segments = $^{4}C_{2}$

= $\frac{4!}{2!2!}=\frac{4\times 3\times 2\times 1}{(2\times 1)\times (2\times 1)}$

= $\frac{4\times 3}{2\times 3}=\frac{12}{2}$

= 6

Option D 6 is the answer.

FOR AN EXAM DUE TODAY!!! Simplify the polynomial. 3x – 2x2 + 4 – x2 + x + -

Mashutka [201]

Answer:

${ \tt{ \blue{ - {3x}^{2} + 4x + 4 }}}$

Step-by-step explanation:

${ \tt{3x - {2x}^{2} + 4 - {x}^{2} + x }} \\$

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

$= { \tt{( - 2 - 1) {x}^{2} + (3 + 1)x + 4 }} \\ = { \boxed{ \tt{ \: - {3x}^{2} + 4x + 4}}}$

If you drew a horizontal line on the coordinate plane, what could you say about the y-coordinate for every point on the line?

sattari [20]

It's the y intercept.
If y = a then every point on the line would be (x,a)
The lines slope is 0. I know that has nothing to do with the question, but it is true and it gives me 3 things to tell you.
