combustion

always exothermic w/ Co2 and 2h2o

sufluric acid

h2SO4

nitric acid

hNO3

hydrochloric acid

HCl

phosphoric acid

precipitate

when a solid is formed from combination of 2 solutions

combustion

Co2 + h2O

always exothermic

chemical reaction

when matter combines or breaks apart to form new kinds of matter w/ different properties

energy

anything that is not matter but can cause a change in matter

law of conservation of energy

energy cannot be created or destroyed

law of conservation of matter

matter cannot be created or destroyed

\-exception is nuclear power when a little is destory and it accounts for HUGE amounts of energy

catalyst

speed sup chemcial reaction without being used by lowering activation energy

enthalpy

change asociated w/ chemcial reaction

exothermic

heat/eenrgy lost, temp will go up

\-reactants have more energy than product

endothermic

heat/energy gained

colder

bunsen burner

too much air no flame and too little will be smokey and yellow

2-3 inch inner blue cone

diatomic

N, I, H, Cl, O, Br, F

Octane

measure of how much compression a fuel can withstand before igniting
