Studied by 3 peoplehydrogens reaction to a burning splint
makes a popping noise
oxygens reaction to a burning splint
reignite the fire
nitrogens reaction to a burning split
the fire will be extinguished
carbon dioxides reaction to a burning splint
the fire will be extinguished
sublimation
solid to gas
disposition
gas to solid
solid to liquid
melting
liquid to solid
freezing
liquid to gas
evaporation
gas to liquid
condensation
alkali metals chemical properties
react to both atmospheric oxygen and water vapour
alkaline earth metals chemical properties
all react to water except beryllium, oxidize, highly reactive
halogens chemical properties
highly reactive, form acids when combined with hydrogen
noble gases chemical properties
odorless, inert, colorless, nonflammable, and are neutral gases that have low chemical reactivity
viscous
high viscosity like honey
not viscous
low viscosity like water
inert
unable to move, not chemically reactive
is helium an inert gas?
yes it is because all noble gases are inert
are alkaline earth metals less reactive than alkali metals?
they are because they have one more valence electron than alkali metals
transpiration
water vapour from a plant to evaporation
