CHM110H5 October Midterm: Tips
1. The periodic table first 40 elements and also 52 & 53
2. Revisit the side otes i the tetooks aout fats ad uestios like: “What is the
contribution of this person (for example, Marie Curie), etc. These can be asked and a
brief description is expected (a line or two)
3. Thee is ve little ultiple hoie as Poë does’t eall like to give ultiple hoie
4. Expect short answer question such as:
- Molality vs. molarity
- How you can tell you tell isotopes apart? / Why do isotopes exist?
- The difference between ionic and covalent bonds answer with the description and
an example of each to show the difference
5. Expect a big calculation question like stoichiometry, Poë really likes limiting reagent
questions so definitely expect a limiting reagent stoichiometry question. Practice it!
6. Redox question. Be able to:
- Identify oxidation and reduction reagents
- Also, be able to identify which is being oxidized/reduced
7. There could be a question like:
- Which of the these have more electrons?
- , , ,  [N^3-, F, O^-, Ne^+]
- The answer is ; [N^3-] it has the most electrons
- , ,  [F, O^-, Ne^+] have the same number of electrons so is isoelectric -> can
ask which ones are isoelectric or also can be asked to rank in order of neutrons/just
ak thigs i ode of soethig…
8. Know the density of water = 1.000g/mL
9. Know some strong acids and bases
- Some strong acids include: , , ,  [HF, HCl, HNO3, H2SO4]
- Some strong bases include: , , ,  [NaOH, KOH, LiOH,
Mg(OH)2]
10. Know solubility rules

Document Summary

These can be asked and a brief description is expected (a line or two: the(cid:396)e is ve(cid:396)(cid:455) little (cid:373)ultiple (cid:272)hoi(cid:272)e as po does(cid:374)"t (cid:396)eall(cid:455) like to give (cid:373)ultiple (cid:272)hoi(cid:272)e, expect short answer question such as: Also, be able to identify which is being oxidized/reduced: there could be a question like: (cid:1840)(cid:2871) , , (cid:1841) , (cid:1840)+ [n^3-, f, o^-, ne^+] The answer is (cid:1840)(cid:2871) ; [n^3-] it has the most electrons. Some strong acids include: , (cid:1829), (cid:1840)(cid:1841)(cid:2871), (cid:2870)(cid:1841)(cid:2872) [hf, hcl, hno3, h2so4] Some strong bases include: (cid:1840)(cid:1841), (cid:1837)(cid:1841), (cid:1838)(cid:1841), (cid:1839)(cid:4666)(cid:1841)(cid:4667)(cid:2870) [naoh, koh, lioh, [nacl, nh4cl, etc. : also know naming of molecular compounds, nomenclature and the written names. Most soluble anion = (cid:1840)(cid:1841)(cid:2871) [no3^-] (nitrate, very soluble) Can get question like rank these three in terms of solubility -> (cid:1840)(cid:1829), (cid:1840)(cid:2872)(cid:1829), etc. Ex. (cid:1829) [hcl] = hydrochloric acid -> know how to write any of them whether given.
