Answer:
ummmmmmmmmm what's that???
<h2>The required "options are (II), (III), and (IV)".</h2>
Explanation:
Postulates of Dalton's atomic theory which are scientifically accepted are:
- Atoms are indestructible.
- Compounds are combinations of different atoms.
- A chemical reaction changes the way atoms are grouped together.
Postulates of Dalton's atomic theory which are not accepted scientifically are:
- All atoms of the same elements are identical.
The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.
The accepted model of the atom was changed.
The concentration of diluted solution is 0.16 M
<u>Explanation:</u>
As, the number of moles of diluted solution and concentrated solution will be same.
So, the equation used to calculate concentration will be:
where,
are the molarity and volume of the concentrated HCl solution
are the molarity and volume of diluted HCl solution
We are given:
Putting values in above equation, we get:
Hence, the concentration of diluted solution is 0.16 M
