Nuclear chem Flashcards
What is formed when a non metal oxide devolves in water
An acid
What is formed when a metal oxide devolves in water
An alkali
What metals react with oxygen
Copper up
mp/bp covalent network
higgh
mp/bp covalent molecule
low
why do atoms have zero charge
same no electrons as protons
when drawing formula, what is different with HINClBrOF elements
they are diatomic- number next to them is 2 ex.H2/O2
how could you collectb a volme of gas
ice cream tub ex|
what metals are extracted by heat alone
mercury silver gold - mercury down - last 3
what metals can be extracted by heat with carbon
zinc iron tin lead copper - zebra ill to learn copper
what metals can be extracted by electrolysis
potassium sodium lithium calcium magnesium aluminum - people say little children make a- first 6
what metals react with oxygen
copper up
what metals react with acid
lead up
what metals react with water
magnesium up
haber process equation
N2+3H2=2NH3
Example of alloys
steel= iron+carbon (increased strength)
conditions for haber process
high pressure
moderate temp-
iron catalyst -speeds up reaction saves energy costs
alkanoic acids can react with what to form salt and water
bases
when a hydrocarbon burns what is produced
co2 and water
why a dc current
going in one direction makes sure only one product bis being produced at each electrode
isomer defonition
same molecular formula but different structure
whole reactivity series in correct order GO!
potassium sodium lithium calcium magnesium aluminum zinc iron tin lead copper mercury silver gold
do covalent substances dissolve in water?
no but in other substances yes
what state is ionic substances at room temp
solid
structure of ionic compounds
ionic lattice
are ionic substances soluble- what page in data book can be used to determine this?
most of them - page 5
do covalent substances conduct
no
are ionic substances soluble
yes!!!!!
