#1
Front (Question)

Molecules

Back (Answer)

combinations of two or more atoms (N2, CO2, NaCI, H2O)

#2
Front (Question)

Atoms held together by bonds (strongest to weakest):

Back (Answer)

• Covalent bond • Ionic bond • Hydrogen bond

#3
Front (Question)

Covalent bond

Back (Answer)

atoms share electrons (CO2)

#4
Front (Question)

Ionic bond

Back (Answer)

atoms bound by electrical attraction (NaCI = Na+ + CI-)

#5
Front (Question)

Hydrogen bond

Back (Answer)

“partial ionic bond” between molecules

#6
Front (Question)

Describe a water compound

Back (Answer)

Partial charges at opposite ends of molecule “Polar” molecule

#7
Front (Question)

High heat capacity

Back (Answer)

measure of amount of heat energy that must be absorbed by the substance to raise the temperature 1 degree C

#8
Front (Question)

Concentrations of H+ (protons) and OH- (electrons) determine pH in an ________ solution.

Back (Answer)

aqueous

#9
Front (Question)

The solution is acidic if

Back (Answer)

H+ (protons) concentration greater than OH- (electrons)

#10
Front (Question)

The solution is basic if

Back (Answer)

OH- (electrons) concentration is greater than H+ (protons)

#11
Front (Question)

T or F: only an acidic solution can be lethal.

Back (Answer)

F: Both an acidic and basic solution can be lethal

#12
Front (Question)

What are examples of high/basic pH?

Back (Answer)

NaOH (sodium hydroxide), ammonia, seawater

#13
Front (Question)

What are examples of low/acidic pH?

Back (Answer)

acid rain, stomach acid, lemon juice, car battery acid

#14
Front (Question)

What are examples of neutral pH?

Back (Answer)

pure water

#15
Front (Question)

What elements are important for soil health and plant growth?

Back (Answer)

calcium, phosphorus, potassium, sulfur, nitrogen, magnesium

#16
Front (Question)

What are the effects of a basic soil?

Back (Answer)

nutrients (e.g., P, Mg) not soluble (unavailable to plants)

#17
Front (Question)

Dark leaves indicates _________ limitation/deficiency

Back (Answer)

phosphorus

#18
Front (Question)

What are the effects of an acidic soil?

Back (Answer)

toxic metal ions (e.g., Al) more available/soluble

#19
Front (Question)

As pH drops/Al availability increases, plants

Back (Answer)

grow slower

#20
Front (Question)

Atoms

Back (Answer)

elemental units (“building blocks of matter”)

#21
Front (Question)

Isotopes

Back (Answer)

Same number of protons, but different numbers of neutrons

#22
Front (Question)

What are the two isotopes of hydrogen?

Back (Answer)

• Deuterium • Tritium

#23
Front (Question)

Deuterium

Back (Answer)

stable isotope (not radioactive; does not disappear)

#24
Front (Question)

Tritium

Back (Answer)

radioisotope (radioactive, spontaneous decay occurs)
