C2d3 has a solubility product constant of 9.14×10−9. what is the molar solubility of c2d3?

1 answer:

4 0

The correct answer for the question that is being presented above is this one:

We need to express the ksp expression of C2D3
C2D3
= (2x)2(3x)3
= 108x5 

Then set that equation equal to your solubility constant 

9.14x10-9 = 108x5 
x = 9.67x10-3

So the molar solubility is 9.67x10-3

Which graph represents the function f(x)= 0.2^x + 3

Dennis_Churaev [7]

The third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation $f(x) = 0.2^{x} + 3$ , we substitute some values in the place of x.

When $x=0,$ $f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.$

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents $f(x) = 0.2^{x} + 3.$

When $x=1,$ $f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.$

The value of f(x) when $x=1$ is lesser than the value of f(x) when $x =0.$

So the third graph or bottom left graph represents $f(x) = 0.2^{x} + 3.$

Can somebody help me with this problem

kati45 [8]

First substitute y=5x+7 so that would turn into 5x+7=6x

Then, isolate/solve for x for 5x + 7 = 6x, in this problem x=7

Substitute x=7 into y=5x+7

y=42

x=7, y=42
(7,42)

-20+1= -19
-19/2= -9.5

Check:
-9.5x2= -19
-19-1= -20
