Give the correct chemical formulas of the products of an acid-base neutralization between H2SO4 and Al(OH)3.  (Numbers will be assumed to be subscripts in your answer.)  Do not try to enter any physical states or coefficients in the answer boxes.  The order in which you list the products does not matter. Formula of one product (do not include the coefficient):  Answer      Formula of other product (do not include the coefficient):  Answer What is the biggest coefficient in the balanced chemical equation for the reaction?  (Report a single digit for your answer.)  Answer

(4b-101) Only using the list of ions below, form two ionic compounds that would be soluble in water, and two ionic compounds that would be insoluble in water. You should make four different compounds, but you may use ions more than once. Be sure to indicate which is which, and make sure your compounds are charge-balanced! Na+ Cour...
