HELP ME PLZ-Label the starting substances “reactants” and the ending substances “products”, then answer the questions that follow: 1. NaHCO3 + HC2H3O2 > CO2 + H2O + NaC2H3O2

2. CaC2 + N2 > CaCN2 + C

3. HAsO3 > As2O5 + H2O

4. FeCl3 + NaOH > Fe(OH)3 + NaCl

See reactions #1-4 above to answer the following:

5. Which reactions are forming (producing) water: &

6. Which reaction is forming an element?

7. Which reaction above is forming table salt (sodium chloride)?

8. Which reaction is forming 3 products?

9. Which reaction has only 1 reactant?

10. How many compounds are in the entire reaction for number 2?

11. How many compounds are in the entire reaction for number 1?

12. Acetic acid (vinegar) is an organic compound with the chemical formula:

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.

my dad did alot of meth and ace cheeks

i think   the answer is c hope i'm right
