HESI CHEMISTRY V1/V2
1. If Hydrogen is in a compound, what would its oxidation number be?
+1
2. What is the oxidation number of any simple
ion?The same as the charge of the ion
3. How many kilograms are in
a pound?0.453592 kg
4. What isthe temperature for freezing point of water in
Celsius?0 degrees Celsius (32°F for Fahrenheit)
5. What isthe conversion of Celsius to Fahrenheit?
5F=9C+160 (remember 5F because you have 5 fingers on a hand & 9C because
catshave 9 lives)
6. What is the oxidation number of an element atom?0
7. What is the freezing point of sea water in Fahrenheit?
Below 0C (pick and answer choice around -2C, actual temp depends on how much
saltis in the water)
8. How many amino acids are in a
dipeptide?2
9. If Oxygen is in a compound, what would its oxidation number be?
-2
10. Which of the following pH values would lemon juice likely
have?2 because the lower the pH value, the more acidic
11. What is a pentose?
A 5 carbon sugar (Pent = 5) (ose =
sugar)
12. What is the oxidation state of the Sulfur atom in Sulfuric Acid H2SO4?
6 i(each iH iis i+1, ieach iO iis i-2. iAll icharges ihave ito iadd ito i0. i2+S-
8=0, iso iS=6)
13. How many neutrons does carbon 14 have?
8 ( mass# - atomics # = neutrons) 14 - 6 =
8
,14. How many protons does Potassium
, have?1i 9 i(same ias ithe iatomic inumber)
15. How many amino acids are essential for human
life?20 amino acids
16. Normal body temperature in
°C?37°C
17. Normal body temperature in
°F?98.6°F
18. Boiling point of water in
°C?100°C
19. Boiling point of water in °F?
