If it requires 18.2 milliliters of 0.45 molar barium hydroxide to neutralize 38.5 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 yields ba(no3)2 + h2o

0.42 M

Explanation:

The expression used will be :

where,

= basicity of = 1

= acidity of = 2

= concentration of = ?

= concentration of = 0.45 M

= volume of = 38.5 ml

= volume of = 18.2 ml

Now put all the given values in the above law, we get the concentration:

By solving the terms, we get :

Therefore, the concentration of is 0.42M

if you're asking what comes out, it's steam.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
