100
anything that has mass and takes up space
What is matter
100
a testable conjecture that proposes an answer to the question
What is a hypothesis
100
solid, liquid, and gas
What are the states of matter
100
a unique one- or two-letter designation of an element. EX: O for Oxygen, and Zn for Zinc
What is a chemical symbol
100
a process that occurs when one or more substances are changed into one or more new substances
What is a chemical reaction
200
the study of the composition of matter and the changes that matter undergoes
What is Chemistry
200
a systematic and logical approach to the acquisition of knowledge
What is the scientific method
200
the gaseous state of a substance that is a solid or liquid at room temperature
What is vapor
200
H2O
What is the chemical formula for water?
200
a substance that is present at the start of a chemical reaction
What is a reactant
300
Macroscopic is things that you can see, touch, and measure directly. Microscopic are small particles that make up matter.
What is the Difference between Macroscopic and Microscopic
300
1.formulate question 2. make hypothesis 3. experimentation 4. analyze results 5. develop theories and revisit hypothesis
What are the steps of the scientific method
300
matter that has a uniform and definite composition. All samples of pure substances have identical properties
What is a pure substance
300
Composition is uniform throughout Ex:air, salt water, sugar water, brass, solutions
What is a Homogeneous Mixture
300
a substance that is present at the end of a chemical reaction
What is a product
400
Organic chemistry involves carbon, Inorganic chemistry does not involve carbon
What is the difference between Organic chemistry and Inorganic chemistry
400
an explanation that has been repeatedly tested and confirmed by multiple researchers and has gained wide acceptance
What is a theory
400
a property that depends on the amount of matter in a sample
What is a extensive property
400
Composition is not uniform throughout the mixture Ex: soil, sand and water mixture
What is a Heterogeneous Mixture
400
the ability of a substance to undergo a specific chemical change
What is a chemical property
500
the study of the composition of matter, with a focus on separating, identifying, and quantifying chemical samples
What is analytical chemistry
500
Two individuals who personified the Renaissance approach to science
Who is Leonardo Da Vinci and Nicolas Copernicus
500
property of matter that depends only on the type of matter in a sample and not on the amount
What is a intensive property
500
Filtration, Distillation, Crystallization, and Chromatography
What are the four techniques to separate a mixture
500
a solid product that forms from a reaction and settles out of a liquid mixture
What is precipitate
