What is the difference between a natural and artificial diamond ​

Engineering
2 answers:
IgorC [24]3 years ago

Answer:

So, if natural and synthetic diamonds have the same makeup, are there any differences?

Synthetic diamonds do differ from natural stones, but not as far as their fundamental structure is concerned. The main difference that can be observed is in the clarity of the stones.

Whereas most natural diamonds have internal flaws that occurred during the stones’ formation, synthetics tend to be cleaner.

This is because they are created through a controlled process designed to minimize defects, and as a result, there are fewer flaws in the crystal structure of synthetics

Answer:

Lab-grown diamonds are created in a laboratory, often produced in just a matter of weeks. There is a tiny chemical difference between the two, as natural diamonds often contain a very small amount of nitrogen, while synthetic diamonds do not.Nov 23, 2020

What Are 2 Properties electromagnets have that permanent magnets do not?
NikAS [45]

Answer:The distinction between a permanent magnet and an electromagnet is essentially one in how the field is created, not the properties of the field afterwards. So electromagnets still have two poles, still attract ferromagnetic materials, and still have poles that repel other like poles and attract unlike poles.

A 13.7g sample of a compound exerts a pressure of 2.01atm in a 0.750L flask at 399K. What is the molar mass of the compound?a. 3
Katarina [22]

Answer: Option D) 298 g/mol  is the correct answer

Explanation:

Given that;

Mass of sample m = 13.7 g

pressure P = 2.01 atm

Volume V = 0.750 L

Temperature T = 399 K

Now taking a look at the ideal gas equation

PV = nRT

we solve for n

n = PV/RT

now we substitute

n = (2.01 atm x 0.750 L) / (0.0821 L-atm/mol-K x 399 K )

= 1.5075 / 32.7579

= 0.04601 mol

we know that

molar mass of the compound = mass / moles

so

Molar Mass = 13.7 g / 0.04601 mol

= 297.7 g/mol  ≈ 298 g/mol

Therefore Option D) 298 g/mol  is the correct answer

python Given num_rows and num_cols, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E.
MissTica

Explanation:

First of all get the input from the user, number of rows and number of columns where rows represents seat digit number and column represents the seat letter

rows is initialized to 1 to ensure that row starts at 1 or you can remove it then seat number will start from 0.

The first loop is used for digits starting from 1 to number of rows

The second loop is used for letters starting from 1 to number of columns

since rows and cols are not of the same type that's why we are converting the int type to string type

print(str(rows)+cols) counter will keep updating the columns A, B, C.....

rows= rows + 1 counter will keep updating the rows 1, 2, 3....

Code:

Please refer to the attached image.

Output:

Please enter the number of rows: 2

Please enter the number of columns: 3

1A

1B

1C

2A

2B
