what is a heterogeneous mixture
you can see what is mixed in the solvent
what is a homogeneous mixture
you cannot see the differences

no
do suspensions show the tyndall effect
yes
do colloids show the tyndall effect
yes

no
what is solvation
process of surrounding solute particles with solvent particles to from solution
what do polar substances dissolve
other polar substances
what do non polar substances dissolve
other non polar substances
what is the universal solvent
water
what makes water conduct electricity
ionic compounds that are dissolved in it bc ionic compounds breakdown into ions
what is an electrolyte
ionic compound that conducts electricity and dissociates in solution
what is a non electrolyte
covalent compounds that do not dissociate and do not conduct electricity
A+B–>AB
redox/synthesis
AB–>A+B
redox/decomp
AB+O2–> AO+BO or CH+O2–> CO2+ H2O
redox/combustion
