What is the solubility of Copper (II) Oxalate in pure water?The solubility equilibrium (Ksp) is 2.9 x 10⁻⁸ so the solubility can be found as:
Ksp = [Cu²⁺] [C₂O₄²⁻]
Solving gives:
2.9 x 10⁻⁸ = S x S
S² = 2.9 x 10⁻⁸
S = 1.7 x 10⁻⁴ M

The value of solubility for cuc2o4(s) in pure water when the value of solubility product, Ksp for it is 2.9 ×10⁻⁸, is 1.703 × 10⁻⁴.
What is solubility?The solubility of a chemical compound or an element is the property or ability of it to be dissolved, specially in water.
The solubility for CuC₂O₄(s) in pure water has to be found out. The solubility product is,
[tex]K_{sp}=2. 9 \times 10^{-8}[/tex]
Let suppose x is the molar solubility of CuC₂O₄(s). From the ICE approach solution,
[tex]K_{sp}=x^2\\2. 9 \times 10^{-8}=x^2\\x=\sqrt{2. 9 \times 10^{-8}}\\x=1.703 \times 10^{-4}\rm\; M[/tex]
Thus, the value of solubility for cuc2o4(s) in pure water when the value of solubility product, Ksp for it is 2.9 ×10⁻⁸, is 1.703 × 10⁻⁴.

Answer:
(6, 0)
Step-by-step explanation:
Coordinates are written in the form (x, y), where x is the x-axis value that the point is in, in this case 6, and where y is the y-axis value, in this case 0.
Hi!
Answer:
(6, 0)
Step-by-step explanation:
Coordinate point "G" on this graph is on the very bottom. On the X axis, point G is on the 6. On the Y axis, its on the 0, so since the domain, (X) comes first before the range, (Y), you get (6, 0)

Chuck brought $40.00 to the state fair. He bought a burger, a souvenir, and a pass. The burger was 1 /4 as much as the souvenir, and the souvenir cost 2 /3 the cost of the pass. Chuck had $1.50 left over after buying these items.
Answer:
Souvenir = £14
Burger = £3.50
Pass = £21

f(x)=x^2. what is g(x)?
A. g(x)= 3x^2
B. g(x)= (1/3x)^2
C. g(x)= 1/3x^2
D. g(x)= 1/9x^2
Answer:
See Down Here
Step-by-step explanation:
We want to get g(x) given that we know f(x) and the graphs for both functions. We will see that the correct option is D:
g(x) = (x/3)^2
By looking at the graph we can see that f(x) and g(x) are two quadratic functions, and g(x) is just a dilation of f(x).
This means that:
g(x) = A*f(x)
Where A is a real number.
We know that:
f(x) = x^2
And by looking at the graph, we also know that g(3) = 1.
Then we can write:
g(3) = A*f(3) = A*3^2 = 1
Now we can solve this for A:
A*3^2 = 1
A*9 = 1
A = 1/9
Then we have:
g(x) = (1/9)*f(x) = (1/9)*x^2 = (x/3)^2
So the correct option is D.

Lan make 60 cakes. he gives 1/4 of the cakes to Helen. he gives 20 of the 60 cakes to sue. what fraction of the 60 cakes does he have left?
Answer:
5/12
Step-by-step explanation:
1/4 × 60 = 15
He gave 15 cakes to Helen.
He gave 20 cakes to Sue.
20 + 15 = 35
He gave away a total of 35 cakes.
60 - 35 = 25
He has 25 cakes left.

What is the value of x when 1/4x=14 3/4 ?
Answer:
x = 59
Step-by-step explanation:

Angle one and two lie on straight line.
this means there sum is equal to 180°
Given :-
angle 1 = 7x angle 2 = x+12so we can say :-
[tex] \angle1 + \angle2 = 180 \degree \\ 7x + x + 12 = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{ \cancel{168} {}^{ \: \: 21} }{ \cancel8} \\ x = 21 \degree[/tex]
so angle one = 7x= 7×21 = 147°
angle two = x+12 = 21+12 = 33°
1. Solve the following formulas
a. Solve the formula 8x + y = 15 for y.
b. Solve the formula 9x + y = 13 for y.
c. Solve the formula −4x + y = − 6 for y.
d. Solve the formula −5x + y = − 1 for y.
[tex]\textbf{a)}\\\\~~~~~~8x+y = 15\\\\\implies y = 15-8x\\\\\textbf{b)}\\\\~~~~~~9x+y = 13\\\\\implies y = 13 -9x\\\\\textbf{c)}\\\\~~~~~-4x+y = -6 \\\\\implies y = 4x -6 \\\\\textbf{d)}\\\\~~~~~-5x +y = -1\\\\\implies y = 5x -1[/tex]
Step-by-step explanation:
1. 8x+y=15
y=15-8x
2. 9x+y=13
y=13-9x

Don't worry about the x and w, I just need the answer to y. Find the value of y if JKLM~PQRS
Answer:
y = 15
Step-by-step explanation:
JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.
In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.
This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.
Solving for y.
Angle J is congruent to angle P.

A researcher is interested in whether using mental imagery can help people remember specific details when given information. To conduct the experiment, the researcher asks 100 volunteers to participate. The researcher places everyone’s name in a hat and randomly selects 50 names, making sure to sure to mix the names between each selection.
Which component is missing from the researcher’s process?
The researcher did not use enough randomization in the process.
The researcher used volunteers instead of randomly selected people from the population.
The researcher did not assign the 50 names to the treatment group or the control group.
The researcher should have used numbers instead of names for confidentiality reasons.
The researcher ought to have divided the volunteers into two groups; the treatment group and the control group at random.

Help can you help me with angles please ＞﹏＜
===========================================================
Explanation:
There are two approaches here.
Method 1
Focus on the numbers along the top only.
The left arrow points at 50 while the arrow on the right points at 180. Subtract these numbers to get 180 - 50 = 130
------------------------------
Method 2
Focus on the numbers along the bottom row this time.
The left arrow points at 130 and the right arrow points at 0
The difference of which is 130 - 0 = 130
Because we're subtracting off 0, it means we can simply look at only one number without having to do any math. This only works if the other portion of the angle is pointing at 0 or 180.
------------------------------
Notice that 130 degrees is larger than 90, so this angle is obtuse. This means that if you aren't sure whether to go with 50 or 130, it will depend on if it's acute or obtuse.

Find the residual values, and use the graphing calculator tool to make a residual plot. A 4-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled given with entries negative 3.5, negative 2.9, negative 1.1, 2.2, 3.4. The third column is labeled predicted with entries negative 1.1, 2, 5.1, 8.2, 1.3. The fourth column is labeled residual value with all entries blank. Does the residual plot show that the line of best fit is appropriate for the data? Yes, the points have no pattern. No, the points are evenly distributed about the x-axis. No, the points are in a linear pattern. Yes, the points are in a curved pattern.
The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern
X Given Predicted Residual value

3 1.1 0.12 0.98
4 2.2 -1.85 4.05
5 -4.1 -3.82 -0.28
The residual value is calculated as follows using this formula: ( Given - predicted )
1) ( 3.5 - 4.06 ) = -0.56
2) ( 2.3 - 2.09 ) = 0.21

Solve the following inequality for x. -5x < -15x + 40 a. x > -2.00 b. x > 4 c. x < 4 d. x < -2.00
Answer:
c. x < 4

-5x < -15x + 40
bring -15x to the left to combine like terms
-5x +15x < -15x + 15x + 40
