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:

i think   the answer is c hope i'm right

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
