Answer:
2
Explanation:
In calcium oxide, the calcium is electropositive in nature and to fulfil its octet, the calcium atoms lose two electrons to form the calcium cations whose valency is 2, hence the corresponding anion, i.e. the oxide anion must also have valency 2 to balance the positive charge on the calcium cation.

The number of atoms in Barium (Ba) is 1
Answer:
133 mL
Explanation:
M= mol solute/ L solution
mol solute= M *L solution
mol solute = (2.0 M * 0.4 L)
mol solute= 0.8 mol HCl= mol H
We need the same amount of OH moles to neutralize the solution
L solution = mol solute/M
L solution= 0.8 mol Ba(OH)2/ 6M
L solution=0.133 L=133 mL
Alcohol should be the answer to help you out with that question!
