Explanation:
A solution with pH less than 7 will be acidic in nature and it will change color of blue litmus into red.
For example, HCl is a strong acid as it dissociates to give hydrogen ions and chlorine ions.
A solution with pH more than 7 will be basic in nature and it will change color of red litmus into blue.
A solution with pH equal to 7 will be neutral in nature and it will not change the color any litmus paper.
Thus, we can conclude that in a 0.01 M solution of HCl, litmus will be red.
Answer:
it is 92
Explanation:
Atomic Mass 238.029 atomic mass units
Number of Protons 92
Number of Neutrons 146
Number of Electrons 92
Answer:
92
Explanation:
because it is the 92nd element on the table it has 92 protons
a. 8
b.16
c.32
d.64
32 Electrons
In statement the letter "n" specifies the Principle Quantum Number. Principle Quantum number is main energy level of an atom. Hence, n = 4 means we are talking about the fourth energy level or fourth shell of an atom.
Also, the number of electrons present in any main energy level are calculated by using following formula,
2n²
Hence, as,
n = 4
So, by putting this value in above formula,
2 (4)²
2 (16)
32
The maximum number of electrons that can be accommodated in the n=4 shell is 32.
(Option C).
The maximum number of electrons that can be accommodated in the n=4 shell can be determined using the following formula.
maximum electrons = 2n²
where;
The given parameters include;
n = 4
The maximum number of electrons that can be accommodated in the n=4 shell is calculated as;
maximum electrons = 2n²
maximum electrons = 2 (4²)
maximum electrons = 32

This is a "Exothermic Reaction."
I did the same test and this was the correct answer.
I hope this helps!
