Answer:
The answer is 0.005.
Step-by-step explanation:
<u>When you divide any number by 10, you move the decimal point over to the left by </u>1 place.
If, for example, you were instead multiplying by 10, your answer would change to 0.5.
3+p=8
-p -p
3=8-p
-8 -8
-5=-p
swap signs
5=p
If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.
With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).
The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.
If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.

Thank you for posting your question here at brainly. To answer the above question,
First calculate the Joules (work done by Alexander), divide by 4.184 to get calories and then divide by 1000 to get kilocalories or Calories.
<span>201 lbs will be 90 kgs approx. And work done will be mgh = 90 x 10 x 5220 kg.m Double that for coming down.</span>
Answer:
1/4
Step-by-step explanation:
Distribute.
7 - 7y = -3y + 6
Get all ys on one side
7 = 4y + 6
Get constants all on one side.
1 = 4y
Divide
1/4 = y
