Explanation:
yes you got the right idea
A. density
<span>Reaction rate increases with concentration.</span>
Magnesium + Hydrocloric acid -> Magnesium chloride + hydrogen
You can observe a single displacement reaction
"Describe to show that the has formed is hydrogen"
I don't know what you mean. I can show the chemical equation though.
Mg(s) + 2 HCl(aq) --> MgCl 2(aq) + H 2(g)
Answer:
It's true.
Explanation:
In sub-energy level : number of orbitals
