balancing equations & types of reactions

H, N, O, F, Br, Cl, I (acronym: hungry ninjas order fresh chocolate brownies instantly)

name the diatomic elements (molecule composed of two of the same atom)

to follow the law of conservation of mass

why do we balance equations

matter cannot be destroyed or created

define the law of conservation of mass

synthesis

putting things together & getting one product

decomposition

one reactant, breaks it apart

single replacement

same elements, new ordering. leaves one element remaining (element + compound)

double replacement

can only replace like things w/ like things. ordering is always pos then neg

combustion/organic combustion

adding oxygen & resulting in large amounts of heat & light. always produces CO2 & H2O

precipitate

solid that forms when solutions are mixed is called...

precipitation reactions

...always apply to double replacement

salts

positive & negative pattern in double replacement always referred to as...

solubility

means the ability to be dissolved, especially in water

group 1 metals, nitrate, acetate, ammonium, Cl-, Br-, SO4²-

solubility rules contain: (name the metals and polyatomic ions)

except w/ Ag, Hg, Pb

name the exceptions for solubility for Cl-, Br-, I-

except w/ Ag, Hg, Pb, Ca, Sr, Ba

name the exceptions for solubility for SO4²-

group 1 metals & ammonium, group 2 Sr & Ba

OH- is insoluble except the soluble salts of...

charge

net ionic equation must include...

net ionic equation

the chemical equation that shows only those elements, compounds, & ions that are directly involved in the chemical reaction
