The Co2+ concentration in a saturated solution of cobalt(II) hydroxide is measured and found to be 3.86×10-6 M. Use this information to calculate a Ksp value for cobalt(II) hydroxide.
The number of bonds an element tends to form can be referred to as its valence, and typically corresponds to how many electrons that element needs to complete its octet. These rules will always hold true for hydrogen and fluorine, and generally will ..
Problem- How many milliliters of a 1.0 M bromine (Br2) in CH2Cl2 solution are there in 1.1 molar equivalents of the N, N- dimethylaniline (above). How many moles are there in 7.0mL of N, N- dimethylaniline
