| Front | What charge does the hydrogen atom have in a water molecule? |
| Back | Slightly positive charge |
| Front | Explain how the unsaturated bonds affects the melting points of triglycerides |
| Back | -Unsaturated bonds contain one or many double bonds between the carbon atoms in the hydrocarbon chain of the three fatty acids -These double bonds causes the tail of the three fatty acids to bend therefore pushing the unsaturated molecules further apart than the saturated molecules. As a result, this creates weak intermolecular forces therefore resulting in a low melting point |
| Front | Explain why cellulose is strong |
| Back | -Because the cellulose long chains are parallel the hydroxyl (-OH) groups are in close proximity-Hydrogen bonds are cross-linked between the slightly negatively charged oxygen atom and slightly positively charged hydrogen atom in each cellulose chain forming thousands of hydrogen bonds therefore making cellulose strong |
