Answer:
600 mL
Explanation:
From the question given above, the following data were obtained:
Initial concentration (C₁) = 6 M
Initial volume (V₁) = 50 mL
Final concentration (C₂) = 0.5 M
Final volume (V₂) =?
Using the dilution formula (i.e C₁V₁ = C₂V₂) we can obtain the final volume as illustrated below:
C₁V₁ = C₂V₂
6 × 50 = 0.5 × V₂
300 = 0.5 × V₂
Divide both side by 0.5
V₂ = 300 / 0.5
V₂ = 600 mL
Thus, the final volume is 600 mL
Bromine, it's the only element that isn't a metal
Calcium carbonate (), an insoluble precipitate that could be removed from water by filtration, is created when the calcium ion in hard water bonds with the carbonate ion.
Precipitates may be ionic solids that are insoluble and result from reactions between certain cations as well as anions in water. A precipitate's formation could be influenced by a variety of circumstances.
When calcium atoms gain or lose electrons, they change their charge but also reactivity, forming calcium ions.
Therefore, Calcium carbonate (), could be used to precipitate the calcium ion form a water sample
