Fusion and fission are both nuclear reactions that produce energy, but fusion is two nucleus joining (think about fuse or fusing), while fission is a nucleus splitting (think about fissure)
so the correct answer is <span>C. Fission is the splitting of a nucleus</span>
Answer:
Bacteria decompose rotting plant animal material.
Explanation:
Theres good bacteria, and theres bad bacteria. some helps, and some makes things worse. so really, in some sense all of the above.
Hope that helps.
Answer:If a bouncing ball has a total energy of 20 J and a kinetic energy of 5 J, the ball’s potential energy is 15J.
If the kinetic energy of the ball decreases, then the potential energy will Increase.

Answer:
0.056moles HF and 0.70M
Explanation:
When a strong acid is added to a buffer, the acid reacts with the conjugate base.
In the system, NaF and HF, weak acid is HF and conjugate base is NaF. The reaction of NaF with HCl (Strong acid) is:
NaF + HCl → HF + NaCl
Initial moles of NaF and HF in 60.0mL of solution are:
NaF:
0.0600L × (0.80mol / L)= 0.048 moles NaF
HF:
0.0600L × (0.80mol / L)= 0.048 moles HF
Then, the added moles of HCl are:
0.0200L × (0.40mol / L) = 0.008 moles HCl.
Thus, after the reaction, moles of HF produced are 0.008 moles + the initial 0.048moles of HF, moles of HF are:
<em>0.056moles HF</em>
<em></em>
In 20.0mL + 60.0mL = 80.0mL = 0.0800L, molarity of HF is:
0.056mol HF / 0.0800L = <em>0.70M</em>
Hexane<span> would be non-polar and since water is a polar solvent it wouldn't be </span>soluble<span>in water. ... Because it is totally non polar while water is exactly the opposite being very polar. The old saying says like </span>dissolves<span> like. </span>
