X is girl, and y is boy, they are formed by fission.
Ludmilka [50]3 years ago
3 0

Answer:

3: Atoms X and Y will have a smaller atomic mass than atom Z

7: Fissile

8: It is used in nuclear power plants

Explanation:

3

The process of nuclear fission is where one unstable atom (in this case atom Z) splits into two smaller atoms (atoms X and Y) and releases energy in the form of radiation.

Hence, the combined atomic mass of X and Y cannot be grater than the mass of atom Z, fission does not need to be at high temperatures to take place, and the mass of element X will never equal the mass of element Z.

7

In nuclear fission, the energy is produced by the decay of radioactive elements, and that energy can not be obtained by <u>combustion</u>. Stable elements will not undergo fission, and low mass elements tend to be very stable too.

8

The energy produced from nuclear fission is not always controllable, that is why disasters such as nuclear meltdowns happen, because the energy output cannot be controlled. The atoms in the sun undergo fusion, and not fission. Once again, nuclear fission does not require high temperatures (nuclear fusion does, hence why the sun has such a high temperature).

Uranium has an atomic weight of 238 amu.
shepuryov [24]

Answer:

U= 238g/mol

U2O5= 556g/mol

Explanation:

Since U= 238

O=16

U3O5= 2(238)+3(16)=556g/mol

What features did you use to classify igneous rocks as extrusive or intrusive ?
umka21 [38]

Answer: Igneous rocks may be simply classified according to their chemical/mineral composition as felsic, intermediate, mafic, and ultramafic, and by texture or grain size: intrusive rocks are course grained (all crystals are visible to the naked eye) while extrusive rocks may be fine-grained (microscopic crystals) or glass.

Explanation: Hope this helped! :)

A container of N, 03(9) has a pressure of 0.490 atm. When the absolute temperature of the N, O2(g) is tripled, the gas
spayn [35]

Answer: 1.59atm

Explanation:

We have that for the Question "Calculate the final pressure of the gas mixture, assuming that the container volume does not change."

it can be said that

The final pressure of the gas mixture, assuming that the container volume does not change =

From the question we are told

A container of N2O3(g) has a pressure of 0.265 atm. When the absolute temperature of the N2O3(g) is tripled, the gas completely decomposes, producing NO2(g) and NO(g).

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press
Simora [160]
Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases

Have a nice day!
