Including the alkanes, oils , fats and greasy substances in general
Isotopes are basically from the same element. In terms of subatomic particles of the element, the isotopes will then basically have the same number of protons. The electrons also have to be same in number given that the elements are in neutral charges.
We are then left with neutrons, which is one of the subatomic particles residing in the nucleus of an atom.
Thus, the answer is NEUTRONS.
<span>Ca(NO3)2 (aq) + Na2SO4 (aq) --> CaSO4 (s) + 2NaNO3 (aq)
Ca2+ (aq) + 2NO3- (aq) + 2 Na+ (aq) + SO4 (aq) --> CaSO4 (s) + 2Na+ (aq) + 2NO3- (aq)
cancel out spectator ions
Ca2+ (aq) + SO4 (aq) ---> CaSO4 (s hope it helps</span>
Answer:
By using renewable energy sources.
Explanation:
You need to satisfy a quota of energy for (whatever country you live in). People do this by using the cheapest way of producing the most energy, the most efficient. Sounds great right? Wrong! It stuffs our atmosphere with harmful gasses like carbon dioxide. You can reduce the use of these fossil fuels by using renewable energy sources such as windmills, watermills, and most notable, solar panels!
