The reaction that would beat represent a typical reaction mechanism is when A and B react with each other to produce certain products.
Answer: Thus X is Plutonium
Explanation:
Alpha Decay: In this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. The mass number is reduced by 4 units and atomic number is reduced by 2 units.
General representation of alpha decay :
where Z = atomic number
A= mass number
X and Y = atomic symbol of elements
Thus 
Thus X is Plutonium with atomic number 94 and mass number 239
Answer: It is a Lewis acid/base reaction, and 
is the Lewis acid.
Explanation:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
can readily accept electrons and thus act as a lewis acid which is short of electrons.
can readily lose electrons and thus act as a lewis base which has excess of electrons.
It is a Lewis acid/base reaction, and is the Lewis acid.
Answer:
The correct answer is 24.31 amu.
Explanation:
The formula for finding the average atomic mass = The sum of the percentage abundance of isotopes × the actual mass of isotopes
The average atomic mass = % abundance of Mg-24 × actual mass + % abundance of Mg-25 × its actual mass + % abundance of Mg-26 × its actual mass
Avg. Atomic mass = 0.7870 × 23.98504 + 0.1013 × 24.98584 + 0.1117 × 25.98259
Avg. atomic mass = 18.88 + 2.53 + 2.90 = 24.31 amu
The atomic mass of magnesium is 24.31 amu.
