chemistry fuels Q&A

?
what is the correct term for polymeristation?
poly(ethene)
1 of 32
what is the one thing polymerization used for?
making plastics.
2 of 32
what is polymerization?
it is all about making a longer chain of carbon atoms molecules. they can have millions of carbon atoms.
3 of 32
name 1 problem with polymerization?
they are not biodegradable meaning that micro-organisms are not able to break it down.
4 of 32
name another problem with polymerization?
when you burn polymers you will release toxic gases into the air.
5 of 32
name the final problem with polymerization?
we can recycle polymers but sometimes it takes to long in order to put them into categories.
6 of 32
what is cracking used for?
it is used to make shorter chains of molecules from bigger ones.
7 of 32
why is cracking needed?
it is needed so we are able to keep up with the demand for hydrocarbons that we need more of.
8 of 32
alkenes and alkanes what are they forms of?
alkenes and alkanes are all different forms of hydrocarbons.
9 of 32
what type of bonds do alkanes have?
they have a single bond
10 of 32
what type of bonds do alkenes have?
they have a double bond.
11 of 32
name three forms of alkanes?
methane, ethane and propane.
12 of 32
what reacts with hydrogen to create energy?
oxygen
13 of 32
do you have to use water or turbines to generate electricity?
no because when you react the two elements together you get electricity in the process and water.
14 of 32
are any greenhouse gases made?
no the only waste product is water.
15 of 32
what are bio fuels?
they are fuels which are made from organisms and plants.
16 of 32
how can electricity be made by bio gas?
the bio gas is able to boil water which turns a turbine which generates electricity.
17 of 32
what is the only waste product?
carbon dioxide + water
18 of 32
name 2 advantages that come from using bio fuels?
1) is that it is a renewable source of energy. 2) it reduces the amount of co2 generate by humans.
19 of 32
name 2 disadvantages in using bio fuels?
1)requires crops in order to produce bio fuels. 2) also increases food prices and takes a lot of energy to do so.
20 of 32
name one way we can reduce the amount of carbon dioxide in the atmosphere?
by adding iron seeding to oceans this will encourage plant growth winch use co2 in order to photosynthesize.
21 of 32
name one way both methane and carbon dioxide are effecting the worlds atmosphere?
they are heating up the climate.
22 of 32
how can deforestation affect the amounts of co2 levels in the atmosphere.
when we burn the trees we release carbon dioxide into the atmosphere.
23 of 32
when does carbon monoxide can carbon form in incomplete combustion?
they occur when there is not enough oxygen present in a area making carbon monoxide and carbon.
24 of 32
why is carbon monoxide so dangerous?
because it effects the amount of oxygen that is in are bodies. it also blocks of oxygen in an area.
25 of 32
why do you get a yellow flame?
you get a yellow flame when the carbon soot burns and causes it to burn and therefore you get the yellow flame.
26 of 32
what gases are released when burning hydrocarbons?
sulfur oxide, carbon dioxide, carbon monoxide and carbon.
27 of 32
how does carbon dioxide effect the worlds atmosphere?
by trapping warm air and not letting it escape.
28 of 32
name 2 effect winch sulfur oxide does?
when it is released into the atmosphere it causes acid rain winch pollutes lakes as well as corrodes metals.
29 of 32
name one way in which we can reduce the amount of sulfur in the atmosphere.
by fitting cars with catalytic converts as well as removing the sulfur from the hydrocarbon.
30 of 32
name on effect of carbon?
clogs up pipes.
31 of 32
name one effect of carbon monoxide?
a colorless odurless compound which is able to stop the supply of oxygen into the body.
