21
Q

in a flame test, what colour flame would barium give?

A

pale green

22
Q

describe the test for chlorine

A

any indicator paper gets bleached if positive

23
Q

describe the test for hydrogen

A

wen exposed to a flame, a test tube of hydrogen gives a squeaky pop

24
Q

describe the test for carbon dioxide

A

when combined with lime water, turns milky

25
Q

carbonate ion

A

2-

CO3

26
Q

what colour flame would magnesium have?

A

white

27
Q

what colour flame would sulfur have?

A

blue

28
Q

describe the color change from copper carbonate to copper oxide

A

green–>black

29
Q

describe the properties of CO2

A

colour less
odorless
slightly soluble than water
denser than air

30
Q

how is carbon dioxide used in fire extinguishers

A

the dense gas sinks onto the flames and prevents oxygen from combining with them

31
Q

Carbon dioxide + water –> ?

A

carbonic acid - H2CO3

32
Q

sulfur dioxide + water –> ?

A

sulfurous acid - H2SO3

33
Q

describe the reaction of water with magnesium

A
  • vigorous reaction
  • mixture gets hot
  • colour less solution formed
34
Q

describe the reaction of aluminum with dilute acid

A
  • slow at first but after warming reacts vigorously

- due to protective layer of aluminum oxide on the surface

35
Q

describe the reaction of dilute acid with zinc

A
  • slow but more rapid with heating
36
Q

describe the reaction of iron with dilute acids

A
  • slow but more rapid with heating
37
Q

describe a chemical test for water

A

water present in a mixture will turn anhydrous copper sulphate from white to blue

38
Q

list the reactivity series from most to least reactive

A 
Potassium        Provoking
Sodium             Seductive
Lithium             Language
Calcium            Can
Magnesium      Manipulate
Aluminum         Anyone
Carbon             Careful
Zinc                  Zapping
Iron                   Induces
Hydrogen         Heated
Copper             Conversations
Silver                 Stay
Gold                  Guarded
39
Q

what can be used to prevent the rusting of iron

A

paint
oil
grade
plastic

aka the barrier method

40
Q

describe galvanizing iron

A

metals more reactive than iron can be used as sacrificial metals as they react instead of it

galvanizing iron - coating iron with a layer of zinc

41
Q

if you get a blue precipitate upon adding NaOH to x, what is x?

A

Cu2+

42
Q

if you get a red/brown precipitate upon adding NaOH to x, what is x?

A

Fe3+

43
Q

if you get a green precipitate that slowly turns brown upon adding NaOH to x, what is x?

A

Fe2+

44
Q

if your product is warm, smells of ammonia, and turns red litmus paper blue, what did you add NaOH to?

A

NH4+
