Answer:
the answer is c because it can be either greatly increased or decreased
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.

Answer:
3:23 to 3:24
Step-by-step explanation:
explantion between these to points the slope of the graph hits 3:24 hard
Cos(Angle) = Adjacent leg / Hypotenuse
Cos(X) = 3.5/4.6
X = arccos(3.5/4.6)
X = 40.46 degrees.
Answer:
No, this result is not surprising. It is a little bit more than one standard deviation above 20%
Step-by-step explanation:
Proportion of each color in the population (p) = 0.20
Sample size (n) = 20 Skittles
The standard deviation of a sampling distribution is determined by:
The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
