explain element
element contain only one type of particles called atom
. in an element the atom are all the same
. any substance listed on the periodic table is an element
define compound
contain two or more different elements that are bonded together in a fixed ratio giving each compound a fixed chemical formula
define mixture
mixture is a substance were two or more elements or compound are added together but the proportion of each can vary
what is a solvent
solvent as a substance that dissolve a solute
what is a solute
a substance that is dissolved in a solvent
what is a solution

what is a solube
able to be dissolved especially in water
what is an insoluable
not able to be dissolved
what is salt
mixture of acid and base
what is inorganic solute
sea water contain sodium chlorine potassium magnesium sulfur calcium
what is salanity
amount of dissolved salts present in sea water
what is the normal salanity of sea water
35ppt
why sea water is salty
due to dissolved salts
factors increase salanity
evoporation
temperature
less rain fall
factors that decreases salanity
precipitation
run off
melting of ice sheet
what are the factors effecting salanity
erosion
run off precipitation and evoparation
explain why there is a greater rain fall there is a increased of run off but that the concentration of dissolved salt in river is so low
it is caused by the saddition of fresh water rather than the removal of salt in water
in which area is dissolved oxygen is more
at the surface due to atmosphere contact, photosynthesis
in cold water
