The First Ionization energy of Nitrogen is greater (Not smaller)than that of Phosphorous. This is because going down the group (N and P are in same group) the number of shells increases, the distance of valence electrons from Nucleus increases and hence due to less interaction between nucleus and valence electrons it becomes easy to knock out the electron.
<span>The second ionization energy of Na is larger than that of Mg because after first loss of electron Na has gained Noble Gas Configuration (Stable Configuration) and now requires greater energy to loose both second electron and Noble Gas Configuration. While Mg after second ionization attains Noble Gas Configuration hence it prices less energy.</span>
Molar mass of Neon ( Ne ) = 20.1797 g/mol
m = n * mm
m = 125 * 20.1797
m = 2522.4625 g
hope this helps!
Its total charge is zero but for the elements:
Sn===> Sn4+ positive
Cl===> Cl- negative
Answer: a. Synthesis
Explanation:
a. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example: 
Thus magnesium in its elemental form is combining with oxygen to form magnesium oxide.
b. Double displacement reaction is one in which exchange of ions take place.
Example: 
c. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example:
