If it requires 23.4 milliliters of 0.65 molar barium hydroxide to neutralize 42.5 milliliters of nitric acid, solve for the molarity of the nitric acid solution. show all of the work used to solve this problem. unbalanced equation: ba(oh)2 + hno3 ba(no3)2 + h2o

we know that it takes 2 moles of HNO3 to neutralize and each mole of Ba(OH)2 and the total number of moles of Ba(OH)2 to be neutralized is
23.4*10^(-3) litres * 0.65 mol/litre
= 15.21*10^(-3) moles
[ 2*15.21*10^(-3)
= 30.42*10^(-3) moles] of HNO3 in a volume of 42.5 ml
The molarity is 30.42*10^(-3) moles / 42.5*10^(-3) litres
= 0.72 C
hope it helps

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
