3 0

Answer:

-  \frac{4}{5}

Step-by-step explanation:

Please see the attached picture.

slope \\  =  \frac{1 - ( - 3)}{ - 3 - 2}  \\  =  \frac{1 + 3}{ - 5}  \\  =  -  \frac{4}{5}

☆In the gradient formula,

(x1, y1) is the first coordinate and (x2, y2) is the second coordinate.

If x represents the molar solubility of b a 3 ( p o 4 ) 2 , what is the correct equation for the k s p ?
AnnyKZ [126]

The molar solubility of Ba₃(PO₄)₂ is its concentration of pure substance

The correct equation for the ksp is Ksp = 6x⁵

<h3>How to determine the equation of ksp?</h3>

Start by writing the reaction for the solution of Barium phosphate

Ba₃(PO₄)₂  ⇌3Ba²⁺ +2PO₄³⁻

Next, we make an ICE chart

Let "x" be the molar solubility of Barium phosphate

          Ba₃(PO₄)₂(s)  ⇌3Ba²⁺ +2PO₄³⁻

I                                 0                  0

C                              +3x               +2x

E                                3x³                 2x²

Lastly, we write the expression for the solubility product constant (Ksp)

This is represented as:

Ksp = [3Ba²⁺] × [2PO₄³⁻]²

Ksp = 3x³ × 2x²

Evaluate the product

Ksp = 6x⁵

Hence, the correct equation for the ksp is Ksp = 6x⁵

Ratling [72]

Answer:

from the given info

you can know that there were 16 red ones. (2/3)*24

and 8 green apples

and her classmates ate 3/4 of red ones i.e.

(3/4)*16

=12

and 1/2od green

i.e.

(1/2)*8

=4

and now the total eaten apples

= 12+4

=16

and the remaining number are

24-16

=8

Share 160 sweets in the ratio 8:12
katrin [286]

let's divide the whole by the sum of its ratios, namely let's 160 ÷ (8+12), and then distribute accordingly.

\bf \textit{160 at 8:12 ratio}\qquad \qquad \cfrac{8\cdot \frac{160}{8+12}}{12\cdot \frac{160}{8+12}}\implies \cfrac{8(8)}{12(8)}\implies \cfrac{64}{96}
