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>

Hi Veracity,

Answer:

(2 + i) = 2

Step-by-step explanation:

Multiply the denominator and numerator by the conjugate,

= \frac{(8 - i)(3 + 2i)}{13}

Combine Like Terms,

= \frac{26 + 13i}{13}

Simplify,

= 2 + i

Hope This Helps :)

Consider the sequence Two-fourths, three-fifths, four-sixths, StartFraction 5 Over 7 EndFraction, ellipsis Which statement descr
Phoenix [80]

Answer:

The sequence converges to 1

Step-by-step explanation:

Given

\frac{2}{4}. \frac{3}{5}, \frac{4}{6}, \frac{5}{7},...

Require

Description of the sequence

The given sequence follows:

\frac{2}{4}. \frac{3}{5}, \frac{4}{6}, \frac{5}{7},... \frac{n+1}{n+3}

i.e.

T_n = \frac{n+1}{n+3}

For every term,

\frac{n+1}{n+3} < 1

In other words,

as the value of n increases, \frac{n+1}{n+3} approaches 1

<em>Hence, (c) is true</em>

4.5*10^-8/9*10^-9 find the quotient and write it in scientific form
g100num [7]

Answer:

5

Step-by-step explanation:

4.5*10^-8/ 9*10^-9

1) Reduce the fraction, express 9 as a product of multiplying 4.5*2

4.5*10^-8/4.5*2*10^-9

2) Then notice the common factor of numerator and denominator( 4.5) , get rid of it in both numerator and dnominator

3) 10^-8/ 2*10^-9= 1/2*(10^-8/10^-9)= 0.5* (10^-8/10^-9)

10^-8/10^-9= 10^(-8-(-9))= 10^1=10.

so 0.5*10=5 (it is the answer written in scientific form)
