Carbon Footprint Flashcards
What does a large molecule include?
High Boiling Point.
Doesn’t flow easily.
Hard to ignite.
How much oxygen does incomplete combustion include?
Limited Oxygen
Is Crude oil renewable?
No (Finite).
If there is a abundant supply oxygen, carbon turns into what?
It turns into carbon dioxide.
If there is a limited supply of oxygen, carbon turns into what?
It turns into carbon monoxide.
What can incomplete combustion produce?
Carbon monoxide, carbon, carbon dioxide, water.
What is it called when crude oil is heated?
Fractional distillation.
What is the formulae for an alkane?
H=Cn2+2.
In Combustion what does hydrogen, oxide into?
Water.
What happened when the number of carbons increases in an alkane?
The boiling point increases.
Definition of Polymerisation?
Large molecules made up of small repeating units.
What is the difference between an Alkane and an Alkene?
Allene’s have a double bond and Alkanes have a single bond.
What do monomers turn into when they reach a high temperature?
Polymers.
What is crude oil?
A mixture of hydrocarbons (fossil fuel).
How much oxygen does complete Combustion include?
Plenty of oxygen.
What temperature is crude oil heated too?
400 °C.
What is the formulae for an alkene?
H=Cn2.
What does a small molecule include?
Low Boiling Point.
Flow easily.
Easy to ignite.
Definition of Boiling Point.
The temperature where liquid starts to become gas.
What happens to the particles in a substance when boiling occurs?
They seperate and the bond holding them together starts to break.
Does a Covalent Bond transfer any charge?
No.
What is the boiling point of methane?
-161 °C.
Can Carbon form an ion?
No. But it can form Covalent Bonds.
Definition of Covalent Bonds.
Shared pair of electrons.
As you go up the fractionating column what decreases?
The boiling point and size of each molecule decreases.
What happens to chain lengths as the boiling point increases?
The chains get longer.
Where does the heat come from in the distillation column.
Hotter at the bottom and cooler at the top.
What is a boiling point?
The temperature where a solid starts to become a gas.
What temperature is room temperature?
22 °C-28 °C.
