HESI CHEMISTRY V1/V2 - QUESTIONS AND
ANSWERS
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 is the temperature for freezing point of water in
Celsius? 1 degrees Celsius (32°F for Fahrenheit)
5. What is the conversion of Celsius to Fahrenheit?
5F=9C+160 (remember 5F because you have 5 fingers on a hand
& 9C because cats have 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 salt is 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 (each H is +1, each O is -2. All charges
have to add to 0. 2+S-8=0, so S=6)
