Answer:
2M
Explanation:
Given parameters:
Number of moles of FeCl₃ = 0.3 moles
Volume of water = 150mL
Unknown:
Molarity of solution = ?
Solution:
The molarity of a solution is the number of moles of solutes in a given solution. It is one of the ways of expressing concentration. The unit is always M i.e mol/dm³.
Molarity =
Express the volume in dm³;
150mL gives 0.15dm³
Molarity =
= 2M
Break until new rock is formed
The type of change is chemical change. This reaction yields compounds with different identities that is carbon dioxide,Calcium chloride and water
Explanation:
FeCl3 + <u>3</u> KSCN ➡ <u>3</u> KCl + Fe(SCN)3
