Answer:

14 electrons can occupy the f sub level

Explanation:

Electronic configuration is the short representation which we use to represent the structure of an atom.

Atomic number of phosphorus is 15 so it has 15 electrons.

The electronic configuration of Phosphorus is given as $1s^2 2s^2 2p^6 3s^2 3p^3$

Here the superscript number represents the electrons 2 + 2 + 6 + 2 + 3 = 15 electrons of Phosphorus

Orbital diagram too is used for this purpose.

A circle or a square is used to represent an orbital.

This is the orbital diagram of Radon (atomic number -86)

Each orbital occupies 2 electron.

Shells are named using letters K, L, M, N and so on or using numbers 1, 2, 3, 4 etc.,

The number of electrons, a shell can accommodate is found using formula $2n^2$ where n is the number of the shell.

Shell 1 contains subshell s

Shell 2 contains subshell s, p

Shell 3 contains subshell s, p, d

Shell 4 contains subshell s, p, d, f

Subshells or sub level are represented by letters s, p, d, f, g, h, i and so on.

s contains 1 orbital with 2 electrons

p subshell contains 3 orbital with 6 electrons

d with 5 orbitals and 10 electrons

f with 7 orbitals and 14 electrons.

Which of the following is a sign a chemical reaction has occurred? A liquid changes to a solid when cooled. A liquid forms bubbl

3241004551 [841]

The best answer is, “Two clear liquids combine and turn cloudy.”

When water freezes form a liquid to a solid. That’s a physical change.

When water boils, it forms bubbles. That’s a physical change.

When you mix ethanol and water, they form a clear solution. That’s a physical change.

A sample of the mineral hematite Iron (III) oxide has a mass of 12.4g. How many moles of the mineral are present?

8090 [49]

Thus problem is providing us with the mass of iron (III) oxide as 12.4 g so the moles are required and found to be 0.0776 mol after the calculations:

<h3>Mole-mass relationships:</h3>

In chemistry, we use mole-mass relationships in order to calculate grams from moles and vice versa. In this case, since we are given the mass of iron (III) oxide as 12.4 g one can calculate the moles by firstly quantifying its molar mass:

$Fe_2O_3\rightarrow 2*55.85 g/mol+3*16.00 g/mol=159.7g/mol$

Then, we prepare a conversion factor in order to cancel out the grams and thus, get moles:

$12.4gFe_2O_3*\frac{1molFe_2O_3}{159.7gFe_2O_3} \\\\=0.0776molFe_2O_3$

7. Which two substances do geologists use in radiocarbon dating?

Sav [38]

Carbon -14 and Carbon 12 are the two substances geologists use in radiocarbon dating.

Answer: Option B

Explanation:

Radiocarbon dating denotes the determination process of the age of fossils of plants or animals based on the ratio of carbon atoms 14 to 12. Carbon naturally exists in two non-radioactive isotopes, Carbon-12 and Carbon-13 and one radioactive isotope carbon 14. The carbon 14 gets released on continuous cosmic reaction with atmospheric nitrogen.

These carbon 14 will be absorbed by the living plants and from the plants. Then, it will enter inside the animals which consume the plants. But once the plants and animals died, they ceased to intake carbon-14. In their living state, the ratios of carbon atoms 14 to 12 in them tends to similar to the ratio in atmosphere.

But after they die, the ratio of C-14 to C-12 will be varying from the ratio of C-14 to C-12 in atmosphere as the concentration of C-14 will be decreasing in the dead animals and plants. Thus using this ratio, geologists can find the fossil's age.

In an experiment, hydrochloric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was form

iris [78.8K]

Answer:

I think that the trend that would be seen in the time column of the data table would be that the number of seconds would increase. I know this because for each flask, the concentration of sodium thiosulfate decreases, since less of it is being mixed with more water. Also, when the concentration of a substance decreases, then the reaction rate also decreases, as there will be fewer collisions with sulfuric acid if there are fewer moles of sodium thiosulfate. When there are fewer collisions in a reaction, the reaction itself will take longer, and so when the sodium thiosulfate is diluted, the reaction takes more time.

Explanation:

I verify this is correct.
