Answer:
Evaporation
Explanation:
Evaporation is the process of a liquid turning into its gaseous form. When a liquid hits its boiling point, it will evaporate and turn into gas. It can release vapor as well.
1)sodium chloride/common salt
2)sodium hydroxide
3)sodium carbonate/washing soda
4)sodium bi-carbonate/baking soda
5)calcium hypochlorite/bleaching power
6)hemihydrate calcium sulphate/plaster of Paris
7)calcium sulfate
8)copper sulfate
9)bororn trifluoride
10)potassium nitrate
I could only find ten examples
The correct answer would be B: 4.
There are 5.35 × 10²⁴ atoms in 8.89 moles of Helium.
<u>Explanation:</u>
Given that number of moles of Helium = 8.89 moles
Moles and Avogadro's number are related to each other by multiplying those two we can convert moles into atoms, molecules and Particles .
We have to convert the moles into atoms by multiplying the molar amount by Avogadro's number as,
Number of atoms = 8.89 × 6.022 × 10²³ atoms
= 5.35 × 10²⁴ atoms
So there are 5.35 × 10²⁴ atoms in 8.89 moles of Helium.
