Write the balanced net ionic equation for the complete neutralization of chromiu

Question

Write the balanced net ionic equation for the complete neutralization of chromium(III) hydroxide with sulfuric acid. Use H^+ rather than H_3O^+. What is the sum of the coefficients? (Do not forget coefficients of one.) 8 11 16 18 22 For the complete neutralization reactions between the following pairs of acid and bases, which pair is a soluble, strong base and a weak acid that react to form a soluble salt? Ca(OH)_2, HNO_3 KOH, H_3PO_4 NH_3HF Ba(OH)_2, H_2CO_3 Fe(OH)_2, H_2S For the complete neutralization reactions between the following pairs of acid and bases, which pair is an insoluble base and a weak acid that react to form an insoluble salt? Ca(OH)_2, HNO_3 KOH, H_3PO_4 NH_3, HF Ba(OH)_2, H_2CO_3 Pb(OH)_2, H_2S For which one of the pairs of acids and bases does the following represent the net ionic equation? H_3O^+ + OH rightarrow 2H_2O NaOH, HBr CH_3COOH, Ca(OH)_2 HNO_3, Mg(OH)_2 CH_3COOH Cu(OH)_2

Explanation / Answer

40.

the molecular

2Cr(OH)3 + 3H2SO4 --> 6H2O + Cr2(SO4)3

the net ionic:

6OH-(aq) + 6H+(aq) = 6H2O(l)
