i think the forces are the same and size and in opposite directions
Explanation:
<h3>Answer:</h3>
Number of Protons = 6
Number of Electrons = 6
Number of Neutrons = 7
<h3>Explanation:</h3>
Number of Protons:
As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.
Number of Electrons:
As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.
Number of Neutrons:
Number of neutrons can be calculated using following formula,
No. of Neutrons = Atomic Mass - Number of Protons
As,
Atomic Mass = 13
So,
No. of Neutrons = 13 - 6
No. of Neutrons = 7
From a stock solution of 3.00 m nitric acid, 9.391 ml of stock solution is needed to create a 0.161 m nitric acid solution, which has a total volume of 175 ml of the diluted solution.
A chemical reagent is present in vast quantities as a stock solution. It has a uniform concentration. Examples of typical stock solutions in laboratories are nitric acid and hydrochloric acid. These play a critical role in creating the titration-related solution preparations.
We know the formula for dilution type problems
M1 VI = M2 V 2
Where,
M, = initial molarity
V , = initial Volume
M2 = final molarity
V 2 = final Volume
Hene given -
M, = 3.00 M
VI = ?
M2 = 0.161M
V 2 = 175 ml
Accordingly ' MI V1 = M2 V 2
V1 =
V1= (0.161M*175ml)/ 3.00M
v1 = 9.391
The required volume of Stock solution is 9.391ml.

Explanation:
sulphur has a low melting point.
sulphur has a low boiling point thus it can be extracted by pumping hot water which turns it ito solution form
Because they do not have the same qualities therefore they are different
