✔ 最佳答案
因為檸檬有檸檬酸 citric acidcitric acid 係 polar
oil 有 hydrophobic tail and hydrophilic head
head 溶左 in acid
當我地 stir 佢既時候
oil break into droplets and will not stick back due to repulsion

your rest of the 2/4 answer:
when we stir it
the oil split into droplets and can't reform back due to the repulsion by the heads
and now i answer back the question
oil(triglycerides) contains 3 fatty acids and 1 glycerol
the bond between them is ester bond
and so oil is called triester

檸檬入面有acids
acids係polar molecules
油係polar molecule既影響下
分解成為正負離子 所以就分解左
