Independent variables don't change
Dependent variables change as a result of the alteration made during the experiment
The answer should be 12 since 4 x 3 = 12
This is because ammonia is NH^3 and if it has a number before it you multiply it with the rest of the chemical equation.
I hope this helps
Answer:-
+1
Explanation:-
Group 1 A compounds has 1 valence electron.
According to the octet rule, if outermost shell has 8 electrons then it is stable.
So Group 1 A compounds lose 1 electron to fulfill octet.
Oxidation number is the number of electrons lost or gained. It is positive if electrons are lost and negative if electrons are gained.
Hence the oxidation number of group 1 A compounds is +1.
