Identifying the 5 Branches in Chemistry
What is mass?
A measure of the amount of matter in an object.
Which branch of chemistry specifically deals with quantitative analysis?
Analytical Chemistry
What is an example of kinetic energy?
Anything that is moving
What is matter?
Anything that occupies space and has mass.
Why do you think charges flow in an electric current?
Electric charges flow when they have electric potential energy. Potential energy is stored energy that an object has due to its position or shape.
True or False? Chemists always specialize in just one of the specific areas of chemistry.
False
The making of new compounds for energy processes is explored in _________ chemistry.
Inorganic
Can matter be created or destroyed?
It may undergo physical or chemical changes.
The synthesization of new carbon compounds is studied in __________ chemistry.
Organic
In ___________ chemistry, the electrical properties of solutions can be measured.
Physical
Is the chemical energy in food kinetic energy or potential energy?
Potential energy. It is stored in the chemical bonds that make up food molecules. The stored energy is released when we digest food.
What is energy?
The ability to move matter or change matter in some other way.
What is Organic Chemistry?
The study of carbon compounds.
What is Biochemistry?
The study of chemical processes that occur in living things. Research may cover basic cellular processes up to understanding disease states so better treatments can be developed.
What is Inorganic Chemistry?
The study of chemicals that do not, in general, contain carbon.
What is Physical Chemistry?
The study of macroscopic properties, atomic properties, and phenomena in chemical systems.
What is Analytical Chemistry?
The study of the composition of matter. It focuses on separating, identifying, and quantifying chemicals in samples of matter.
What Is Thermal Energy?
The total kinetic energy of moving particles of matter
True or False? Biochemistry involves studying the enzymes in cells.
True
True or False? Most of the chemicals found in all living organisms are based on carbon?
True
True or False? One current important area of inorganic chemistry deals with the design and properties of materials involved in energy and information technology?
True
True or False? Chemical reactions either require energy or release energy?
True. The amount of energy needed or released depends upon the structure of the molecules that are involved in the reaction.
Carrie uses an instrument called a spectrophotometer to determine the levels of various chemicals in a sample of drinking water. What area of chemistry is this?
analytical
Drug testing of athletes and other individuals is big business. Complex instruments can be used to test blood and urine samples for very small amounts of drugs that may have been taken illegally. What branch of chemistry does this belong to?
bio-analytical chemistry
Enzymes are large molecules that are present in most living things and are needed in order to ensure that various chemical reactions occur quickly. Some enzymes contain metal atoms, such as copper or magnesium, which are important to their function. What field of chemistry does this belong to?
bio-inorganic chemistry
Robert is researching the chemical reactions that take place during the digestion of certain foods. What area of chemistry is this?
biochemistry
When measuring mercury in seawater, what branch of chemistry does this belong to?
biochemistry
What is an electric current?
flow of charged particles
What kind of energy is released when we burn natural gas?
heat energy and light energy
Kim is investigating a new way to isolate nickel from various nickel-containing rocks and sediment. What area of chemistry is this?
inorganic
When measuring the electrical properties of solutions, what branch of chemistry does this belong to?
inorganic chemistry
What does bio mean?
living
Sam is studying the reactions of a class of compounds called ethers. The formula of one type of ether is CH3 OCH3. What area of chemistry is this?
organic
When studying enzymes in cells, what branch of chemistry does this belong to?
organic chemistry
A _____________ chemist may study such things as the rates of chemical reactions, the energy transfers that occur in reactions, or the physical structure of materials at the molecular level.
physical
Dan's doing a series of reactions in order to measure the amount of heat being released in each one. What area of chemistry is this?
physical
Some chemists are interested in studying the rates of chemical reactions based on the structures of the various substances involved and trying to figure out the step-by-step mechanism of how the reactions occur on the molecular level. Because the chemistry of carbon-containing compounds is so diverse, these chemists often study those compounds exclusively. What branch of chemistry does this belong to?
physical organic chemistry
