UPDATED QUESTIONS AND VERIFIED
ANSWERS GRADED A+
⩥ The same as the charge of the ion. Answer: What is the oxidation
number of any simple ion?
⩥ 0.453592 kg. Answer: How many kilograms are in a pound?
⩥ 0 degrees Celsius. Answer: What is the temperature for freezing point
of water in Celsius?
⩥ 5F=9C+160 (remember 5F because you have 5 fingers on a hand &
9C because cats have 9 lives). Answer: What is the conversion of
Celsius to Fahrenheit?
⩥ 0. Answer: What is the oxidation number of an element atom?
⩥ Below 0C (pick and answer choice around -2C, actual temp depends
on how much salt is in the water). Answer: What is the freezing point of
sea water in Fahrenheit?
⩥ 2. Answer: How many amino acids are in a dipeptide?
,⩥ -2. Answer: If Oxygen is in a compound, what would its oxidation
number be?
⩥ 2 because the lower the pH value, the more acidic. Answer: Which of
the following pH values would lemon juice likely have?
⩥ A 5 carbon sugar (Pent = 5) (ose = sugar). Answer: What is a pentose?
⩥ 6 (each H is +1, each O is -2. All charges have to add to 0. 2+S-8=0,
so S=6). Answer: What is the oxidation state of the Sulfur atom in
Sulfuric Acid H2SO4?
⩥ 8 ( mass# - atomics # = neutrons) 14 - 6 = 8. Answer: How many
neutrons does carbon 14 have?
⩥ 19 (same as the atomic number). Answer: How many protons does
Potassium have?
⩥ 20 amino acids. Answer: How many amino acids are essential for
human life?
⩥ 37°C. Answer: Normal body temperature in °C?
, ⩥ 98.6°F. Answer: Normal body temperature in °F?
⩥ 100°C. Answer: Boiling point of water in °C?
⩥ 212°F. Answer: Boiling point of water in °F?
⩥ -273°C. Answer: 0°K is equal to ___°C?
⩥ A substance that can act as both a base & acid. Answer: The term
Amphoteric means?
⩥ Absolute zero. Answer: What is Kelvin based around?
⩥ Acid. Answer: A compound that is a Hydrogen or proton donor,
corrosive to metals, causes blue litmus paper to become red and
becomes less acidic when mixed with a base is?
⩥ Alloys. Answer: Mixture of 2 or more metals are?
⩥ · Formulas begin with H (Hydrogen)
· Proton Donor. Answer: Acids
