In the analysis step of scientific method, the results gets analyzed.

Explanation:

One of the initial steps in the scientific method is the systematic observation of something happening.
This leads to the scientific step of coming up with an hypothesis. Hypothesis is the explanation made based on evidence that is not really analyzed by doing an experiment.
Hypothesis however, leads to the need to have an experimentation. The results of the experiments are then analyzed. Based on that it can be proved whether the hypothesis was right or wrong.

What is units we used for measuring the radon gas?

lisabon 2012 [21]

Answer:

Bq/m3 (becquerels per cubic meter) or pCi/l (picocuries per litre)

Explanation:

The unit of the International System of Units identified to measure radioactive activity is Becquerelio (Bq) and equivalent to one decay per second.

The Curio (Ci) is also a radioactivity unit, which is still being used in some countries. It owes its name to chemists and chemists Pierre and Marie Curie.

It represents the amount of material in which 3.7 × 1010 atoms per second, or 3.7 × 1010 nuclear decays per second, which is roughly the activity of 1 g of 226Ra (isotope of the chemical chemical element).

The equivalence between the two is:

1Ci= 3,7 × 1010Bq

The specific radioactive activity of a radioactive gas such as radon gas is measured per unit volume and measured in Bq/m3 or pCi/l.

In this case the equivalence is:

1pCi/l= 37Bq/m3

A cyclinder has a volume of 703 cm3 and a height of 18.5 cm. What can be concluded about the cyclinder

Sergio039 [100]

The volume of a cylinder's formula can be used to find the area of the base.

The formula - r2 h, where r is the cylinder's radius and h is its height, determines the volume of a cylinder.

The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula r2h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the material.

The ratio of the base area to the height can be used to calculate the volume of a cylinder

In a particular mass of kau(cn)2, there are 6.66 × 1020 atoms of gold. What is the total number of atoms in this sample?

Vinvika [58]

Total number of atoms in the sample is the sum of number of atoms of all the elements present in the sample.

Number of gold, $Au$ atoms in $KAu(CN)_2$ = $6.66\times 10^{20}$ atoms (given)

From the formula of compound that is $KAu(CN)_2$ it is clear that the number of potassium and gold are same whereas those of carbon and nitrogen are 2 times of them.

So, the number of atoms of each element is:

Number of potassium, $K$ atoms in $KAu(CN)_2$ = $6.66\times 10^{20}$ atoms

Number of carbon, $C$ atoms in $KAu(CN)_2$ = $2\times6.66\times 10^{20}$ atoms = $13.32\times 10^{20}$

Number of nitrogen, $N$ atoms in $KAu(CN)_2$ = $2\times6.66\times 10^{20}$ atoms = $13.32\times 10^{20}$

Total number of atoms in $KAu(CN)_2$ = Number of gold, $Au$ atoms+Number of potassium, $K$ atoms +Number of carbon, $C$ atoms + Number of nitrogen, $N$ atoms

Total number of atoms in $KAu(CN)_2$ = $6.66\times 10^{20}+6.66\times 10^{20}+13.32\times 10^{20}+13.32\times 10^{20}$

Total number of atoms in $KAu(CN)_2$ = $39.96\times 10^{20}$ atoms

Hence, the total number of atoms in $KAu(CN)_2$ is $3.996\times 10^{21}$ atoms.

The terms dilute and concentrated referred to the ____ of a solution

valentina_108 [34]

Answer:

The correct answer is A) Concentration. See the explanation below, please.

Explanation:

We refer to concentration on the ratio between solute and solvent of a chemical solution. In the case of a more dilute solution, there is a higher proportion of solvent than solute and the opposite occurs in a concentrate.
