In an experiment, a 45.0 mL sample of 0.15 M triethylamine, (CH3)3N (aq), was placed in a flask and titrated to the equivalence point and beyond using 0.10 M HNO3(aq), according to the balanced equation below: (CH3)3N (aq) + HNO3(aq) →(CH3)3NH+(aq) + NO3−(aq)

Calculate the pH after the following volumes of HNO3have been added. The Kb of triethylamine is equal to 6.4 × 10-5.

1) 0.0 mL
2) 36.0 mL
3) 67.5 mL
4) 70.0 mL

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
