What can alpha raditation be stopped by
A sheet of paper
1 of 29
What can beta radiation be stopped by
A thin sheet of aluminium
2 of 29
What can gamma radiation be stopped by
Lead
3 of 29
Balance This equation: CH4+O2+CO2+H20
CH4+2[O2]+CO2+2[H20]
4 of 29
What is the bottom number in an perodic table thing represent
Protons and electrons
5 of 29
How would you work out Neutrons
Take away bottom to top periodic table type
6 of 29
Draw Chlorine Electron structure
2,8,7
7 of 29
What is ionic bonding
stealing
8 of 29
What is convalent bonding
bonding between two non metals (sharing)
9 of 29
What is metallic bonding
Only happens between metals. Delocalised cloud of electrons (Great for conductor)
10 of 29
What is polymer
A plastic
11 of 29
What is the mass number
The total amount of neutrons and protons
12 of 29
What is a mole
Its relative formula mass, for example water will have a mass of 18 grams as thats what it is
13 of 29
What is Chromatograthy work
Putting the substance on paper and with another one at the same height to see if it contains that pigment, when the water moves it out the same level pigment means it is they both contain that pigment
14 of 29
How do they separate chromatograthy
By the solubility because some of them are more easier to dissolve than others.
15 of 29
How does gas chromatograthy work
Putting it into a tube and will separate out as they go at different speeds.
16 of 29
What is Mass Spectrometer
Can identifite the mass of the compounds coming out of the other end of the gas chromatography tube
17 of 29
If C2H4 and the whole of C = 24 and H = 4 what is the percentage mass of carbon of the whole structure
24/28 x 100 = 85.7%
18 of 29
Give 3 reasons why you might lose products (yield)
Evaporating off, Might be making other reactions too, Turning back into itself (reversible reactions)
19 of 29
10kg theoretical yield and 7.6kg actual yield calcualte the percentage of yield
7.6/10 x 100 = 76%
20 of 29
what is rate of reaction equation
amount of product formed(reacent used)/time taken
21 of 29
What is the top and bottom number of a perodic table icon
Top = Mass number (Number of protons and neutrons) | Bottom = Atomic number (Number of protons it contains)
22 of 29
participate meaning
be involved; take part.
23 of 29
What is process of heating reaction
Thermal decomposing
24 of 29
Say the limestone process
Limstone (Calcium carbonate) when heated creates calcium oxide when turned into water is calcium hydroxide and when heated turns into CO2 and calcium carbonate
25 of 29
What is part of the limestone process to test calium hydroxide to test what
If you add lots of water to calcium hydroxide when making calcium hydroxide, that is the stranded test for carbon dioxide gas
26 of 29
How can collision happen more
Faster movement, and more particles.
27 of 29
A clump of two particles have to react on the outside before the middle because
The ones that react to being hit they get paired up but can't get to the middle as it is working on the outside first
28 of 29
How to make it spend less time from a reaction clumped up
Cutting it up
