A 0.1393-g sample of an unknown monoprotic acid was dissolved in 29.0 mL of water and titrated with 0.0627 M NaOH solution. The volume of base required to bring the solution to the equivalence point was 18.2 mL. (a) Calculate the molar mass of the acid. (b) After 10.4 mL of base had been added during the titration, the pH was determined to be 5.35. What is the Ka of the unknown acid

answer; talc and gypsum;

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.

girl imma just put my comment here because i need a couple point okurrttt
