Write the formulas of the compounds formed by specified cations with the following anions: OH-, ClO3-, SO3^2-, HPO4^2-. Express your answers as chemical formulas separated by commas. Use the given order of anions. 1)NH4+ 2)Al^3+ 3)Pb^4+

\(\bf\Huge Welcome~to~\color{#00B4ff}{Open}\color{#7cc517}{Study}~!!!\) First one would be \(\sf NH_4OH \) what do you think \(\sf NH_4^++~ClO_3^-=\ ?\)

You have to look at the charge of the anions and cations For example Pb is 4+ and OH is 1- The overal charge needs to be 0 so you would need 4x (OH) to make the overal charge 0. So the formula is \(\sf Pb(OH)_4\)
