C2d3 has a solubility product constant of 9.14×10−9. what is the molar solubility of c2d3?
UkoKoshka [18]
The correct answer for the question that is being presented above is this one:

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

<span>Then set that equation equal to your solubility constant </span>

<span>9.14x10-9 = 108x5 </span>
<span>x = 9.67x10-3 
</span>
<span>So the molar solubility is 9.67x10-3</span>

find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=-3/4x-3
barxatty [35]

Answer:

y = \frac{4}{3} x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - \frac{3}{4} x - 3 is in this form

with slope m = - \frac{3}{4}

the slope of a perpendicular line is the negative reciprocal of m, hence

m_{perpendicular} = \frac{4}{3}

(0 , - 1 ) is the y-intercept ⇒ c = - 1

y = \frac{4}{3} x - 1  ← equation of perpendicular line
