Answer:
d
Explanation:
because is a reducing agent, O 2 is an oxidizing agent.
Answer:
c. Fission and fusion are two processes that release very little amounts of energy.
Explanation:
This statement is false. In fact, both fission and fusion are processes which release very large amounts of energy. The statement can be rewritten as it is true as follows:
"Fission and fusion are two processes that release very large amounts of energy."
Fission occurs when a large nucleus break apart, splitting into smaller nuclei, while fusion occurs when two light nuclei combine together into a larger nucleus. In both cases, the mass of the reactants is larger than the mass of the final products, so some of the mass has been converted into energy, according to Einstein's equation:

where
E is the energy released
is the mass lost in the process
c is the speed of light
Since c is a very large number (
), we see that even a very small mass
causes the released of a huge amount of energy, so both fission and fusion release large amounts of energy.

Sound though open space (and other compressible media) is composed of compression waves. Lack of any such media, such as the vacuum of space means the sound waves have nothing to propagate through. So there would be no sound. <span>it's also virtually impossible since there's no electricity</span>
According to the information given, the Heisenberg uncertainty principle would be given by the relationship

Here,
h = Planck's constant
= Uncertainty in velocity of object
= Uncertainty in position of object
m = Mass of object
Rearranging to find the position

Replacing with our values we have,


Therefore the uncertainty in position of electron is
