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

Taylor is 15 years younger than Marty. Twice Marty’s age added to three times Taylors age totals 205. What are the ages of Taylo

Inessa05 [86]

Answer:

Taylor's age = x = 35 years

Marty's age = y = 50 years

Step-by-step explanation:

Let

Taylor's age = x

Marty's age = y

Taylor is 15 years younger than Marty.

x = y - 15

Twice Marty’s age added to three times Taylors age totals 205.

205 = 2y + 3x...... Equation 1

Therefore, we substitute y - 15 for x in

205 = 2y + 3x...... Equation 1

205 = 2y + 3(y - 15)

205 = 2y + 3y - 45

Collect like terms

205 + 45 = 5y

250 = 5y

y = 250/5

y = 50 years

x = y - 15

x = 50 - 15

x = 35 years

Solving for x

Therefore:

Taylor's age = x = 35 years

Marty's age = y = 50 years

Which best describes the relationship between the lines with equations âˆ’3xâˆ’4y=1 and âˆ’6xâˆ’8y=2?

Tju [1.3M]

The relationship between 3x+4y=1 and 6x+8y=2 is that they are parallel lines.

<h3>What is the slope-intercept form of an equation?</h3>

Any linear equation has the form of y=mx+b

m is the slope of the equation

b is the y-intercept

The easiest way to see the relationship between the two lines is to transform them both into slope-intercept form, which is y=mx+b.

Equation 1 can be rewritten as

3x+4y=1

4y=1-3x

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

Equation 2 can be rewritten as:

6x+8y=2

8y=2-6x

y = $\frac{2-6x}{8}$

Y= $\frac{1-3x}{4}$

In this form, we can easily identify that both lines have a slope of $-\frac{3}{4}$ , but that they have different y-intercepts. Lines will equal slopes but different y-intercepts are parallel.

Therefore, the lines are parallel.

32/8 = 28/x

djverab [1.8K]

32/8=28/x

we multiply by x

x*32/8=28

we multiply by 8/32

x=28*8/32

8 divides by 32

x=28/4=7
