The net ionic equation of the reaction between AgNO3 and CaBr is 2Ag^+(aq) + 2Br^-(aq) ------> 2AgBr(s)
The net ionic equation shows which ions underwent a change in the reaction. It omits the spectator ions. In order to obtain the net ionic equation, we must first write down the molecular equation as follows;
2AgNO3(aq) + CaBr2(aq) --------> 2AgBr(s) + Ca(NO3)2(aq)
Next, we have to obtain the complete ionic equation as follows;
2Ag^+(aq) + 2NO3^-(aq) + Ca^2+(aq) + 2Br^-(aq) ------> 2AgBr(s) + Ca^2+(aq) + 2NO3^-(aq)
Lastly, we put down the net ionic equation in which the spectator ions are omitted as follows;
2Ag^+(aq) + 2Br^-(aq) ------> 2AgBr(s)

as a solution of copper sulfate slowly evaporates, beautiful blue crystals made of cu(ii) and sulfate ions form such that water molecules are trapped inside the crystals. the overall formula of the compound is cuso4 • 5h2o.
There are five molecules of the water of crystallization.
Mass of hydrated copper(II) sulfate CuSO4 · xH2O = 0.755 g
Mass of anhydrous copper(II) sulfate CuSO4 = 0.483 g
Molar mass of hydrated copper(II) sulfate CuSO4 · xH2O = (160 + 18x) g/mol
Molar mass of anhydrous copper(II) sulfate CuSO4 =160 g/mol
Number of moles of hydrated copper(II) sulfate CuSO4 · xH2O = Number of moles of anhydrous copper(II) sulfate CuSO4
Therefore;
0.755 g/(160 + 18x) g/mol = 0.483 g/160 g/mol
0.755 * 160 = 0.483 (160 + 18x)
120.8 = 77.28 * 8.694x
120.8 - 77.28 = 8.694x
x = (120.8 - 77.28)/8.694
x = 5
The formula of the hydrated salt is CuSO4 · 5H2O.

which of the following statistics are unbiased estimators of population parameters?
The statistics which are unbiased estimators of population parameters are:
I. A sample proportion that is used to estimate a population proportion.
II. A sample variance that is used to estimate a population variance.
III. A sample mean that is used to estimate a population mean.
In Statistics, an estimator can be defined as a statistical value (quantity), which is typically used for estimating a given parameter.
On the other hand, an unbiased estimator refers to an estimator with an expected value that is equal to the parameter i.e the value of its bias is equal to zero (0).
Typically, the proximity or closeness of a sample statistics to the population parameters is mainly determined through the use of an unbiased estimator.
Generally, the determinants of a probability distribution are referred to as parameters.
Hence, a normal distribution is determined through the use of the following:
Parameters.Mean of the population.Variance of the population.In conclusion, the statistics which are unbiased estimators of population parameters are:

calculate the frequency in hertz of electromagnetic radiation that has a wavelength of 720.0 nm. (c = 3.00 x 10⁸ m/s)
Considering the definition of wavelenght, frecuency and propagation speed, the frequency of the electromagnetic radiation that has a wavelength of 720.0 nm is 4.167×10¹⁴ Hz.
In a periodic wave the wavelength (λ) is the physical distance between two points from which the wave repeats itself. It is expressed in units of length (m).
The frequency (f) is a measure of the number of cycles or repetitions of the wave per unit of time. Its unit is s⁻¹ or hertz (Hz).
The propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave's disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:
v = f×λ
In this case, you know:
v=c= 3×10⁸ m/sf= ?λ= 720 nm= 720×10⁻⁹ mReplacing in the definition of propagation speed:
3×10⁸ m/s= f × 720×10⁻⁹ m
Solving:
3×10⁸ m/s÷ 720×10⁻⁹ m= f
4.167×10¹⁴ Hz= f
Finally, the frequency of the electromagnetic radiation that has a wavelength of 720.0 nm is 4.167×10¹⁴ Hz.

If the length of is 7 units, the length of is units.
Answer:
I put 7 but im not sure if it correct yet
Explanation:
if point U is on RS but the U to P is 7 units then U must be the midpoint of RS but i have no idea hope this helps
The correct answer in the box is 7. If the length of UP is 7 units, the length of UQ is 7 units.
What is a fraction?A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Every point on the PQ perpendicular bisector, which can be used to define it, has the same distance from P and Q. This is one of its characteristics.
The following provides evidence for this: Think about the shape created if we connect U, P, and Q. PTU and QTU are the two triangles present. Since T is the midway and the leg UT is common, we know that the two T angles are 90 degrees and that PT=TQ. The triangles are equal as a result of side-angle-side, hence UP=UQ.
Therefore, If the length of UP is 7 units, the length of UQ is 7 units.
