Identify the ion ratios needed to form neutral compounds from the ions below. the metal ion (cation) is listed first, and the nonmetal ion (anion) is listed second. make sure to give each ratio in its most simplified form. na+: br– = 1 : one al3+: cl– = 1 : three mg2+: o2– = 1 : one al3+: o2– = 2 : three(i found the answers in the end, so if anybody is in need of the answers i filled them in)

Here are the ratios,

For,
                                                  Na⁺¹ and Br⁻¹
                                                     1     :     1
So,
                                                         NaBr

For,
                                                  Al⁺³ and Cl⁻¹
                                                     1     :     3
So,
                                                         AlCl₃

For,
                                                  Mg⁺² and O⁻²
                                                     2     :     2
Or,                                                 1     :     1
So,
                                                         MgO


For,
                                                  Al⁺³ and O⁻²
                                                     2     :     3
So,
                                                         Al₂O₃

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o
