Magic number is any number in electron shells that suggest stability. It corresponds to total number of electrons in filled electron shells.
If an electron is having magic number, then it forms stable bonds.
Explanation:
The magic numbers are 2,10,18,36,54, 86 and 126. This refers to the total number of electrons that an electron can have when it is completely filled.
Atomic nuclei which carries either of these nucleons have high binding energy as compared to others. Hence, they have high stability. Bonds in such elements are more strong.
Radioactive decay of such elements is very slow.
Eugene Winger coined the term "magic number".
A Neutralisation reaction, the alkali is neutralizing the acid.
Explanation:
The gravitational force between two 50kg objects could be less than the gravitational force between a 50kg and a 5kg object if the two 50kg objects are much farther apart.
Answer:
b) H2CO3
Explanation:
The conjugate acid of HCO3– is Carbonic acid (H2CO3).
Answer:
3.785 L of lye solution needed for 907.185 g of fat
Explanation:
The computation of the number of grams in 2.00 pounds is shown below:
As we know that
One gallon of lye solution needed 2 fats pounds
Also,
1 gallon = 3.785 L
And,
1 lb = 453.592 g
So,
For 2 lb, it is
= 2 × 453.592
= 907.185 g
Therefore
3.785 L of lye solution needed for 907.185 g of fat
hence, the same is to be considered
