From the conservation of mass, matter is not created nor
destroyed. So ponder it this way, for example I put one piece of toast in a
toaster, but when it is done I had two pieces, that makes no sense right? Same
thing with a chemical reaction but in molecular terms, all things must stay constant.
If you put a convinced amount you have to get that quantity back, not less or
not more in broad terms.
The elements in each group have<span> the </span>same<span> number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (</span>group<span> one) </span>has<span> one electron in its outer shell.</span>
Answer:
Low-energy reactants become high-energy products.
Explanation:
In electrolysis, you are forcing a reaction to occur that otherwise wouldn't happen.
You are pumping energy into the system and converting low-energy reactants into high-energy products.
B is wrong. Nature tends to run downhill energetically, so high-energy reactants tend to form low-energy products spontaneously.
C and D are wrong. If an element is unreactive, it stays unreactive, and vice versa. You can't change the nature of an element.
Answer:
other planets and moons in the solar and beyond
Explanation:
NASA aims to find other planets and moons in our solar system, study them comparatively to earth and see if there's a possibility of been colonized by humans.
