Answer:
Explanation:
before the reaction you have N=2 and H=6 after the reaction you have N=2 and H=6 so yes it follows the law
<h2>Answer:</h2>
The mass of the system will remain the same if there is no conversion of mass to energy in the reaction.
<h3>Explanation:</h3>
- If the system is closed, then according to the law of mass conservation the mass of the reaction system will remain the same.
- <u><em>Law of conservation of the mass: In simple words, it is described as the mass of a closed system can never be changed, it may transfer from one form to another or change into energy.</em></u>
- But if the reaction involves energy transfer like heat or light production, in this case, the mass can be changed.
1 valence electron because it is in group 1 of the periodic table of elements. Which is called the alkali metals
