Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
sorry if im wrong
Explanation:
Answer: It is made up of one element
Answer:
Ca^+2
Explanation:
Hence, the correct option is A.
Answer: Therefore, the volume of 0.001 M KI is 61 ml.
Explanation:
The balanced chemical reaction is :
According to the neutralization law,
where,
= molarity of solution = 0.100 M
= volume of solution = ?
= molarity of solution = 0.200 M
volume of solution = 15.25 ml
= valency of = 1
= valency of = 2
Putting in the values we get:
Therefore, the volume of 0.001 M KI is 61 ml.
