Lighter Than Air
This is the state of matter that has neither a definite shape nor a definite volume
Gas
_ H2O -> _ H2 + _ O2
2 H2O -> 2 H2 + 1 O2
One atom or chemical kicks another out of a molecule
Single Replacement
A contact force that slows down objects moving past each other
Friction
This is how pollen gets inside plants
Pollination
This nonreactive gas is the most common ingredient in the troposphere
_ CH4 + _ O2 -> _ H2O + _ CO2
(1) CH4 + 2 O2 -> 2 H2O + (1) CO2
Oxygen and a fuel react, usually creating fire
Combustion
The product of a force and its lever arm
Any animal or force that moves pollen from one plant to another
Pollinator
This gas can also be found as a very cold solid, called "dry ice"
Carbon dioxide / CO2
_ HCl + _ Al -> _ H2 + _ AlCl3
6 HCl + 2 Al -> 3 H2 + 2 AlCl3
Two or more molecules come together to form a larger molecule
Synthesis
The ratio of force applied to a specific surface area
Pressure
Plants are sometimes consumers. Name one plant that eats animals for food.
Venus Flytrap
(pitcher plant, sundew, butterwort... there are a lot!)
These atomic gases do not react with other gases
The noble gases
_ C6H12O6 + _ O2 -> _ H2O + _ CO2
(1) C6H12O6 + 6 O2 -> 6 H2O + 6 CO2
Chemicals in two different compounds trade places
Double Replacement
When a force acts on an object with mass, it experiences _________
Acceleration
The green chemical that allows for photosynthesis
Chlorophyll
This special gas absorbs ultraviolet radiation in the mesosphere
Ozone / 03
_ Fe(OH)3 -> _ H2O + _ Fe2O3
2 Fe(OH)3 -> 3 H2O + (1) Fe2O3
One larger molecule is broken down into smaller molecules
Decomposition
When all the forces acting on an object cancel each other out, we call this _______________
Equilibrium
The word to describe animals that eat both plants and other animals
