- c1 chemistry
- Fractional distilation
- bonding
- Ionic bonding-attraction between 2 opposites. Positive and negative
- Combustion
- equations
- Polymers
- Made when small molecules join together. they are found in plastics
- Monomers-a single molecule
- Polymers-lots of molecules joined together
- Food additivies
- Antioxidants:stops food reacting with oxygen
- Food colours; gives food improved colours
- Flavor enhancers; improves the flavor off food
- Emulsifiers; helps oil and water to mix and not seperate
- hottest point; at top has highest boiling points largest molecules
- coolest point at top smaller molecules lower boiling points
- fractions have hydrocarbons ONLY hydrogen and carbon
- Covalent bonding-attraction between 2 bonds that are the same. Two positives
- Symbol equation is balanced when number of atoms is the same on each side
- positive ions- formed when electrons are lost from atoms
- Craking
- Turns large hydrocarbon molecules into smaller
