Question: speed of light

Answer: 3.00 x 10^8 m/s

Question: capacitance

Answer: the ability of a conductor to store energy in the form of electrically separated charges

Question: If the generator-brake system alone were engaged when the railcar was moving, which of the following graphs would most accurately represent the subsequent speed of the railcar?

Answer: deceleration with exponential decay

Question: do isomers have the same boiling point

more branched ones have

Question: chemical vs physical properties

Answer: A physical property is an aspect of matter that can be observed or measured without changing it. Examples of physical properties include color, molecular weight and volume. A chemical property may only be observed by changing the chemical identity of a substance.

Question: heat of combustion

Answer: the heat of reaction for the complete burning of one mole of a substance

relative heat released tells us about the thermodynamic stability of the compound

less heat means greater stability

Question: Given that water is the solvent for this type of experiment, what is the best site for tritium labeling?

Answer: position one

that is because it is the least reactive position

so we can trace guanine wherever it goes

Question: ka and kb for acids and bases

Answer: for acids: ka > than Kb

for bases kb > than ka
