If barium ions (Ca^2) have a charge of 2 + and hydroxide ions (C1^1) have a charge of 1-, the compound calcium chloride is?
a)Ca2C1
b)CaC1
c)CaC12
d)Ca2C12
Those are "ells" and not "1s".
What's with the barium ions (Ca^2) and hydroxide ions (Cl^1)? Ba ions are Ba^+2 and hydroxide ions are OH^-.
Anyway, the formula for a moleucle must add to zero; therefore, CaCl2 would be +2 for Ca and -2 for Cl and +2 and -2 = 0 so CaCl2 is the proper formula for calcium chloride.
Thanks
