Observations
Unknown C
Metal looking
shiny
light weight
Possibly magnesium
malleable
flexible?
flammable?
Unknown E
sand like
granulated
light weight
random specks
heavier than unknown C
we thinks it is covalent because it possibly is sand
Method
record observations
test electrical conductivity of the substance
dissolve substance in water
test electrical conductivity of new solution
tests
Unknown C
flame test to see if it burns brightly (like magnesium)
electrical conductivity test
melting point test
solubility test
