Flashcards in Industrial Processes, Cracking And Polymerisation Deck (11)
What is cracking?
The process of breaking down long chain alkanes into shorter ones
How do you do cracking
1. Heat to 700 degrees
2. Add silica or alumina
What is an addition polymer?
A long chain molecule that has been formed by the joining of many monomers
What must a monomer contain for addition polymerisation?
A c-c double bond
How does a monomer change during addition polymerisation?
The double bond breaks
What is a liquid that conducts electricity?
What goes to the cathode when h2so4 is electrolysed?
What goes to the anode when h2so4 is electrolysed?
How do you calculate the a,punt of coulombs?
Current x time
What is an electron mole?
1. Think about a half equations
2. The no. of electrons is the no. of electron moles needed to make one mole of atoms
