balance the equation and determine how many moles of baoh are required to completely neutralize .461 mol of hc2h3o2

Mole ratio:

2 HC2H3O2 + Ba(OH)2 = 2 H2O + Ba(C2H3O2)2

2 mole HC2H3O2 1 mole Ba(OH)2

0.425 moles HC2H3O2 ?

0.425 x 1 / 2

= 0.2125 moles of Ba(OH)2

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the answers would be

the first one and the second one
