Matter
solid, liquid, & gas
What are the three primary states of matter?
naturally occurring catalyst
What is an enzyme?
shares electrons
What is a covalent compound?
What is a physical change?
lets lizards 'walk' on water
What is the tendency of molecules to stick together on the surface of a liquid - surface tension (water much stronger surface tension due to polarity of water molecule)?
ability to do work
What is energy?
the molecule that docks in the enzyme
What is the substrate?
gains or loses electrons
What is an ionic compound?
affects the speed of changes
What is a temperature (heat added or taken away)?
attraction of water molecules to another substance
What is adhesion?
heat removed, molecules flying randomly to flowing together
What is condensation?
customized spot where molecules dock
What is the active site?
two non-metals
What is a covalent compound?
physical change, makes a solution
What is diffusion?
attraction of water molecules to each other
What is cohesion?
solid --> gas
What is sublimation?
end result of a reaction with an enzyme
What is a product?
one metal, one non-metal
What is an ionic compound?
one substance breaks up another substance into smaller pieces
What is dissolving?
molecules with asymmetrical areas of charges
What is a polar molecule?
molecules flowing to molecules vibrating in place
What is heat removed to create freezing?
helps or harms
What is medicine helps; poison harms?
forms crystals
What are ionic compounds?
movement of particles
What is the Brownian motion?
intermolecular attractions
What is hydrogen bonding?
