(CH1 Rev, Problem 21)
A student does a chemical reaction with two chemicals. The total mass of the two chemicals is 17.0 grams. When she is done, she finds that the mass of all the chemicals she has collected is now 17.8 grams. The teacher says the student obviously contaminated the experiment with something else. How does the teacher know this? What is the mass of the contaminants?
What is the Law of Mass Conservation and the mass is 0.80 grams?
The charges and names of all three subatomic particles that make up an atom.
What is proton is positive, neutron is neutral, and electron is negative?
Name three of the wavelengths in the light spectrum.
What is gamma rays, x-rays, ultraviolet rays, infrared rays, microwaves, radio waves?
A sample of liquid's volume of 0.013 m cubed in liters.

(CH 1, Problem 10)
The energy of a photon that has a wavelength of 94 nm.
What is 2.1x10^-18 J?
A chemist is making two different compounds from the same two elements: nitrogen and oxygen. To make the first gas, she reacts 14.01 grams of nitrogen and 16.00 grams of oxygen to make 30.01 grams of the first gas, which is composed of one nitrogen atom and one oxygen atom. Suppose she starts with 14.01 grams of nitrogen again but wants to make a gas composed of one atom of nitrogen and three atoms of oxygen. What mass of oxygen should she use so there are no leftovers?
What is 48.00 g of oxygen?

The electrons in Thomas Rutherford's gold foil experiment did this which disproved the 'plum pudding model.'
What is the electrons bounced against different parts of the wall and did not just go through the slit?
The electron of a hydrogen atom is in the n = 1 orbit. It absorbs light with a wavelength of 103 nm and jumps to the n=3 orbit. If the electron of another hydrogen atom is in the n = 3 orbit, what wavelength of light must it emit to get to its ground state?
What is 103 nm?
The mass of a silicon block that has a volume of 0.45 liters.

The electron of one hydrogen atom moves from the n = 4 orbit directly to its ground state. The electron in another hydrogen atom moves from the n = 6 orbit directly to its ground state. Which electron released a photon with the longer wavelength? Which released a photon with the higher frequency?
What is the electron jumping from the n = 4 orbit emits the photon with the longer wavelength. The electron jumping from the n = 6 orbit emits the photon with the higher frequency?
