Intro Chemistry and Review
Describe the difference between applied chemistry and pure chemistry.
What is applied chemistry being the pursuit of chemical knowledge with a goal in mind, and pure chemistry being the pursuit of chemical knowledge for the sake of knowledge?
Determine whether a thought about food is matter and why.
What is no, as it has no mass and takes up no physical space.
Define the nuclear notation variables.
What is the middle being the symbol, the top left being the mass number, the bottom left being the atomic number, and the top right being the charge.
Describe the difference between the three radiation types penetrating power.
What is alpha having low, beta having medium, and gamma having high penetration power.
Barbie's full name is...
What is Barbara Millicent Walters
Convert 50cm3 to ml
What are 50ml?
Name two of the four ways to separate a mixture.
What is evaporation, filtration, distillation, and chromatography?
Determine how many protons, neutrons and electrons are in a neutral atom of Neptunium-239.
What is 93p, 93e, and 146n?
This type of radiation rarely occurs alone and normally follow the other two types.
What is gamma radiation?
This is the only mammal that can fly.
What is the bat?
A scientist is measuring how giving more time on tests increases the scores up to a certain point, but after that point, the scores begin to drop again. Name the independent variable in this study.
What is the time given on tests.
Describe the difference between an intensive property and an extensive property.
What is an intensive property being independent of how much sample there is, while an extensive property depends on how much of the sample is present.
Name the element in hyphen notation that has 0 neutrons.
What is Hydrogen-1?
Describe what alpha radiation consists of and how it affects its charge.
What is a helium nuclei or 2p and 2n, giving it an overall charge of +2 from the p?
This marine animal has three hearts.
What is an octopus?
The 5 traditional areas of chemistry.
What are organic, inorganic, biochemistry, analytical, and physical?
Determine whether you would have a higher weight on the moon and why.
What is no, as gravity is lower on the moon than on the earth.
Determine the number of each subatomic particle in the end element of Uranium-240 gives off 3 particles of alpha radiation.
What is 86p, 92e, 142n?
Compare and contrast fission and fusion with three points for each.
What are fission being unnatural, creating energy and a lot of waste, and occurs with PU and U, while fusion is natural, creates more energy and less waste than fission, and occurs with H. Both create energy and waste, are nuclear reactions, and occur in the nucleus.
This mammal does not have a stomach, its esophagus goes straight into its intestines.
What is a platypus?
Three ways that laws and theories differ.
What are laws describing and theories defining, laws being absolute and theories being changeable, and laws being what happens and theories being why they happen.
Define the Law of Conservation of Mass/Matter.
What is that mass/matter cannot be created or destroyed, only changed.
Put into nuclear notation a neutral atom of Holmium-165 after it gives off 2 particles of alpha radiation.
What is the answer on the board?
