It would be Cu(NO3)2. The NO3 has a negative charge. Copper has a positive 2. In order to have a stable compound, you would need 2 NO3s, which is why there is a 2 outside of the NO3. I hope this helps.
A humidifier putting moisture in the air IS a physical change.
Answer: 500ml
Explanation:
Using the Dilution formula that
C₁V₁=C₂V₂
Where
C₁=the molarity of concentrated solution
= 12 M
V₁ = Volume of the concentrated solution
=?
C₂=the molarity of the diluted solution
=3.0M
V₂= Volume of the diluted solution= 2 liters
Changing 2 liters to millilitres
1000ml= 1 Liters
2Liters=2000ml
Bringing the formulae and inputting the given values
C₁V₁=C₂V₂
12 x V₁= 3.0 x 2000ml
V₁= 3.0 x 2000 / 12
V₁=500ml
Therefore 500ml of 12-molar HCl mst be diluted to obtain 2 Liters of 3.0 Molar HCl.
