Ответ:
Two compounds.
Explanation:
If you have two peaks in your gas chromatograph, this means that you have two compounds.
The gas chromatograph is an instrument that helps identify how many compounds a substance has by observing its behavior against a solid medium through adsorption and the velocity of each compound in it.
Ответ:
option C = all elements are balanced
Explanation:
In given chemical equation all elements are balanced.
Chemical equation:
MgO + 2LiCl → MgCl₂ + Li₂O
This is balanced chemical equation. We can see that there are one Mg atom and one oxygen atom is present in reactant side and also in product side. So, both are balanced.
In case of lithium there are two Li atoms in reactant side and also in product side , it is also balanced.
There are two chlorine atoms are present in reactant side and also in product side. Chlorine atoms are balanced.
