Answer:
The new molarity is 0,1359M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
0,60 M x 0,639 L= C2 x 2,822 L
C2=(0,60 M x 0,639 L)/ 2, 822 L
<em>C2=0,1359 M</em>
0.8g/ml
d=m/v
d=20/25
d=0.8
2. is point source
3. is non point source
1) donate an H+ ion
option 1 is correct
Calcium chloride react with aluminum to produce calcium and aluminum chloride. This reaction takes place at a temperature of 600-700°C.
CaCl2+F2 -> CaF2 + Cl2
Because the molecules have not been in water so they are not moving around each other
