DATA ANALYSIS 1. Use the titration results to calculate the moles of H2SO4 that were used to reach the equivalence point in each trial. 2. Use your titration results to calculate the molar concentration (molarity) of the Ba(OH)2 solution using the molar amount of H2SO4 used in each trial. 3. Convert the mass of the barium sulfate precipitate, formed in each trial, to moles. 4. Use the moles of BaSO4 from 3 above to calculate the molarity of the Ba(OH)2 solution. 5. Compare the results of your calculations from 2 and 4 above with the actual molarity of the Ba(OH)2 solution. Which method of analysis, equivalence point or gravimetric determination, was more accurate in your experiment? Why?

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

that's what i got you can count the number of atoms
