Why is nuclear energy considered a nonrenewable resource?
Nuclear radiation does not run out.
It comes from radiation from the sun.
Uranium ore is replaced on a geologic timescale.
Uranium replenishes more quickly than it is being used.

Answers

Answer:

You could classify nuclear energy as nonrenewable because uranium and similar fuel sources are finite. On the other hand, some people consider nuclear energy renewable because the element thorium and other new technologies may provide infinite fuel needed to power nuclear reactors.

A sample of nitrogen gas contains 8.23 x 10^23 molecules. What is the volume of this sample at STP?

Please show and explain the steps.

Answers

Answer:

30.6 L

Explanation:

Given data:

Number of molecules of nitrogen = 8.23×10²³ molecules

Volume occupy at STP = ?

Solution:

Standard temperature = 273.15 K

Standard pressure = 1 atm

One mole of any substance at STP occupy 22.4 L volume.

Number of moles of nitrogen:

1 mole contain 6.022×10²³ molecules.

8.23×10²³ molecules × 1mol / 6.022×10²³ molecules

1.37 mol

Volume of nitrogen:

1.37 mol × 22.4 L / 1 mol

30.6 L

What is the molar mass of Al(NO3)3 · 3H2O?

Answers

Answer:

Go to your periodic table and look for each element. Find the mass for Aluminum, Nitrogen, Oxygen, and Hydrogen.

After you find those, for each compound you must add them together and find the least amount of sig figs after the decimal point.

For the first compound, Al(NO3)3, you will have a total of

1 Aluminum atom

3 Nitrogen atoms

9 Oxygen atoms

Aluminum has 26.982 g/mol

Nitrogen has 14.007 g/mol

Oxygen has 15.999 g/mol

Now multiply those numbers by the amount of atoms of each element.

(1)26.982 g/mol = 26.982 g/mol

(3)14.007 g/mol = 42.021 g/mol

(9)15.999 g/mol = 143.991 g/mol

now add all of those numbers together, and you see that their least significant figure after the decimal is 3, so round to 3 digits after the decimal point.

26.983 + 42.021 + 143.991 = 212.994

now do the same for the other compound

to start you off.. you have

6 Hydrogen atoms

3 Oxygen atoms

Hydrogen has 1.009 g/mol

Oxygen has 15.999 g/mol

the least significant figure after the decimal point is 3, so round you 3 digits after the decimal point.

after you finish getting your totals, you. until them and find the greatest sig fig over all. comment on this if you need further instruction :)
