Determine how many moles of ba(oh)2 are required to completely neutralize 0.432 mole of hc2h3o2.

The balanced chemical reaction is:

HC2H3O2 (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2

We are given the amount of HC2H3O2 to be used in the reaction. We use this amount as the starting point of our calculations. 

0.432 mol HC2H3O2 (  1 mol Ba(OH)2 / 1 mol HC2H3O2 ) = 0.432 mol Ba(OH)2 needed

Hope this answers the question.

We need 0.216 moles of Ba(OH)2 to completely neutralize 0.432 moles of HC2H3O2.

Explanation:

First we build the equation that represents the reaction between the  Ba(OH)2 and the  HC2H3O2.

2 CH3COOH + Ba(OH)2 = Ba(Ch3COO)2 + 2 H2O

Second, we use the amount of moles giving (0.432 moles HC2H3O2)  in order to calculate the moles of Ba(OH)2 produced, using the coefficients in the equation.

0.432moles CH3COOH x [1 mol Ba(OH)2/ 2 moles CH3COOH]  = 0.216 moles Ba(OH)2

The answer to the question: choose the correct statement.  a) when ethane reacts with fluorine gas the product is less stable.b) addition reactions of unsaturated hydrocarbons and halogens requires a high activation energy.  c)the double covalent bond within unsaturated hydrocarbons requires a lot of energy to break.  d)the double covalent bond within unsaturated hydrocarbons can be broken easily.is: a) when ethane reacts with fluorine gas the product is less stable.
