Order of operations
pemdas
parentahsees
exponents
mulitply or divide
add or subtract

for parenthasees, work inside to out, left to right

so

first one is (2-6) which is equal to -4
next parenthaees is (8/4) which is 2
now we got
[5(-4)+3(2)^2]^2
exponent
2^2=4
now we got
[5(-4)+3(4)]^2
mulitply
5(-4)=-20
3(4)=12
now we got
[-20+12]^2
simplify
-20+12=-8

now we got
[-8]^2

What is the slope of the line that contains the point (-2,6) and (6,-3)?
VikaD [51]
We can find the slope from (y2-y1)/(x2-x1) . So (-3-6)/(6+2) = -9/8

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
