Answer:
0.8 mL
Explanation:
Use the formula M1V1 = M2V2.
Plug the values in.
5(V1) = 0.02(200)
5V1 = 4
V1 = 0.8 mL
Hope this is right, correct me if I'm wrong!
Because the molecular solutions have low melting and boiling points, and do not conduct electricity.
Answer:
OD. 2HCl
Explanation:
A balanced equation needs the equal # of each element on BOTH sides.
By putting a 2 in front of HCl you now have 2 hydrogens on both sides and 2 chlorines. The Ca and CO3 are already balanced.
Remember, 1 mole= 6.022x10^23 atoms, molecules, or formula units.
Answer is 1.42x10^24
