Molar mass of Neon ( Ne ) = 20.1797 g/mol
m = n * mm
m = 125 * 20.1797
m = 2522.4625 g
hope this helps!
Answer: check for a change in total mass during a reaction.
According to the law of conservation of mass during a chemical change the total mass of the products remains equal to the total mass of the reactants: there is not change in the total mass.
During nuclear reactions the mass can change due to the huge release of energy which proceeds from mass change, as per the famous equation ΔE =Δm. c^2.
Answer:
D. a scientific explanation that is agreed on by all scientists and is no longer adjusted as new evidence is found
Explanation:
Scientific theory is an explanation that has been repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results

Answer:
Therefore, when an atom becomes a positive ion is pulls its electrons closer, decreasing is radius moreover, when it becomes a negative ion, it pulls its electrons closer and decreases the radius.
