|
|
What is a chemical change?
|
When substances change into different substances
|
|
|
What is an isotope?
|
When atoms of the same element have a different number of neutrons
|
|
|
What is an element?
|
All are on the periodic table. All are made up of the same type of atom. Each element has a specific number of protons. THE NUMBER OF PROTONS DOES NOT CHANGE (yes that was meant to be in caps)
|
|
|
What is a compound?
|
Two or more elements. They combine in a certain formula. They are bonded together. They are usually unlike the seperate elements that make them up
|
|
|
What is a solution?
|
A homogenous mixture two or more gases, solids, or liquids that are blended equally throughout
|
|
|
Mixture
|
Can be homo- or hetereogenous
|
|
|
What are some physical properties?
|
Size, color, shape, boiling point, attraction to magnet, ability to flow.
|
|
|
What is a physical change?
|
Any change in shape size or state of matter
|
|
|
What is distillation?
|
A process for seperating substances in a mixture y evaporating liquid and recondensing its vapor
|
|
|
What is a chemical change?
|
The change of one substance to another
|
|
|
What is an isotope?
|
when atoms of the same element have a different number of neutrons
|
|
|
What is an element?
|
All are found on the periodic table. All are made of the same type of atom. Each element has a specific number of protons that doesnt change.
|
|
|
What is a compound?
|
Two or more elements. They combine in a certain formula. They are bonded together. They are usually unlike the seperate elements that make them up.
|
|
|
What is a solution?
|
A homogenous mixture two or more gases, liquids, or solids that are blended evenly
|
|
|
What is a mixture?
|
Can be homo or heterogenous
|
|
|
What are groups or families?
|
The vertical rows on the periodic table.
|
|
|
What are rows or periods?
|
The horizontal rows on the periodic table.
|
|
|
What is the atomic number?
|
The number of protons in an atom
|
|
|
Elements, compounds and mixtures all contain atoms. How are they different from each other?
|
Elements = atoms are all the same
Compounds = two or more elements in a fixed ratio (proportion) Mixture = ratio of substances can vary |
|
|
Name some physical properties:
|
Size, color, shape, melting point, boiling point, attraction to a magnet, ability to flow
|
|
|
What is considered a physical change in a substance?
|
Any change in size, shape, or state of matter (the identity of the element or compound does not change)
|
|
|
What is a chemical change?
|
A change of one substance into another substance
|
|
|
What is distillation?
|
A process for separating substances in a mixture by evaporating a liquid and recondensing its vapor
|

|
|
|
How does the Law of Conservation of Mass apply to chemical changes?
|
The mass of all substances present before a chemical change equals the mass of all the substances remaining after the change
|
|
|
What is the Law of Conservation of Mass?
|
Matter is neither created nor destroyed
|
|
|
What is atomic mass?
