different types of chem
carbon-based chemicals used
states of matter
what is gases, liquids, and solids
mixture with an unevenly distributed composition
what is a heterogeneous mixture
simplest form of matter - has a unique set of properties (can't be broken down)
what are elements
2 parts of a chemical reaction
what is a reactant (chemical reaction enters)
what is a product (chemical reaction exits)
No carbon based chemicals used
What is Inorganic chemistry
property that depends on how much matter is in a sample
what is an extensive property
mixture with an evenly distributed composition
what is a homogeneous mixture
contains 2 or more chemically combined elements in a fixed proportion (can be broken down)
what is a compound
elements organized in the periodic table
what are horizontal rows called periods and vertical columns called groups which have similar physical and chemical properties? All are based on their atomic number
processes take place in living things
What is Bio chemistry
a property that depends on the type of matter in a sample
What is an intensive property?
evaporation
what is the water in a solution going in the air
same amounts of everything (has a fixed ratio)
what is a substance
solids are formed when liquids are mixed
what is percipitate
composition of matter
What is Analytical chemistry
a quality of a substance that can be measured without changing its composition
What is a Physical property
distillation
what is a water vapor condensing back into its original solution?
change that produces matter with a different composition than the original matter
what is chemical change
gas is released when substances are mixed
what is effervescence
mechanism, rate and energy transfer occurring when matter undergoes change
what is Physical chemistry
5 physical properties of matter
what is color, luster, malleability, conductivity, and hardness?
how many phases are in a homogeneous mixture
how many phases are in a heterogeneous mixture
what is a single-phase
what is 2 or more phases
difference between elements and substances
why can a substance be a compound or an element and have multiple elements in its composition but an element cannot be broken down into more than one part by chemical or physical means
in any chemical reaction, mass/matter are not created nor destroyed
what is the law of conservation of mass/matter
