Matter is anything that has mass and takes up space
What is Matter
100
is a group that experiences the same conditions as the experimental groups with the exception of the variable that is being tested.
What is the control group?
100
matter that has a uniform and definite composition
What is pure substance
100
a mixture in which the composition is uniform throughout the mixture.
What is homogeneous mixture
100
is a process that occurs when one or more substances are changed into one or more new substances.
What is chemical reaction
200
is something that you can not see and you need a microscope to see it.
What is Microscopic
200
is the variable that is changed during an experiment
What is the independent variable?
200
is a characteristic of a substance that can be observed or measured without changing the identity of the substance.
What is physical property
200
a mixture in which the composition is not uniform throughout the mixture.
What is heterogeneous mixture
200
this is a substance that is presented at the end of a chemical reaction.
What is a product
300
Chemist are the ones who study pure chemistry and research mankind's of chemistry.
Who study's pure chemistry
300
The variable that is observed during an experiment.
What is the dependent variable?
300
is a property that depends on the amount of matter in a sample.
What is extensive property
300
is a method of separating a mixture based on differences in boiling points.
What is distillation
300
is a solid product that forms from a reaction and settles out of a liquid mixture
What is precipitate
400
is the study of chemicals that do not in general contain carbon.
What is Inorganic chemistry
400
It is a statement that summarizes the results of many observations and experiments and to which there are no known exceptions.
What is the scientific law
400
is a property of matter that depends only on the type of matter in a sample and not on the amount.
What is intensive property
400
this is a pure substance containing two or more elements that have been chemically combined in a fixed proportion.
What is a compound
400
is a substance that is present at the start of a chemical reaction
What is a reactant
500
is the study of the composition of matter, with a focus on separating, identifying, and quantifying chemical samples.
What is Analytical Chemistry?
500
a.experiment b.hypothesis c.chance d.theory
What is not apart of the scientific method?
500
Water is a substance because it is containing one thing and no mixtures.
What is pure substance
500
a unique one- or two-letter designation of an element.
What is a chemical symbol
500
describes the ability of a substance to undergo a specific chemical change.
What is chemical property
