Balance the reaction so the same number of each type of atom is on each side. Which option seems balanced to you?
The best answer is, “Two clear liquids combine and turn cloudy.”
When water freezes form a liquid to a solid. That’s a physical change.
When water boils, it forms bubbles. That’s a physical change.
When you mix ethanol and water, they form a clear solution. That’s a physical change.

Explanation:
1.51 x 10²⁵atoms
Explanation:
Given parameters:
Mass of Na = 578g
Unknown:
Number of atoms = ?
Solution:
To find the number of atoms, we must first find the number of moles the given mass contains.
Number of moles = ![\frac{mass}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D)
molar mass of Na = 23g
Number of moles =
= 25.13moles
1 mole of a substance = 6.02 x 10²³atoms
25.13 mole of Na = 25.13 x 6.02 x 10²³atoms
This gives 1.51 x 10²⁵atoms of Na
