<span>Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.</span>
Answer:
Frying an Egg
Explanation:
When chemical bonds are broken or formed, new particles are created. Therefore, frying an egg is a chemical change because it results in the formation of new particles.
Answer:
the ratio of protons to neutrons
Explanation:
Nuclear stability is based on the ratio of protons to neutrons. The nuclear space is made up of protons and neutrons that occupies the nucleus of an atom.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures the stability of the nucleus.
For sodium, Na, the neutron/proton ratio for stability is 12/11.
Any nucleus with a neutron/proton combination different from its stability ratio will be unstable.
Answer:
35.5KJ
Explanation:
Heat transferred (Q) = change in internal energy (∆U) + work done (W)
Q = 30KJ, W = 500Nm = 500J = 500/1000KJ = 0.5KJ
∆U = Q - W = 30 - 0.5 = 25.5KJ
∆U = final energy (U2) - initial energy (U1)
U2 = ∆U + U1 = 25.5 + 10 = 35.5KJ
Answer:
Burning is a chemical process by which two atoms or molecules will combine with each other. In burning, the two atoms or molecules will combine and release energy. ... When the molecules combine and release energy, it is released in the form of heat and often light.
