A student determines the density, solubility, and boiling point of two liquids, Liquid 1 and Liquid 2. Then he stirs the two liq
uids together and heats them. After stirring and heating the liquids, two different liquids form, Liquid 3 and Liquid 4. Then the student determines the density, solubility, and boiling point of Liquids 3 and 4. He concludes that a chemical reaction occurred. Here are his results:

How does the student know that a chemical reaction has occurred?
The student knows that a chemical reaction has occurred because Liquid 3 has different properties than Liquid 4.
The student knows that a chemical reaction has occurred because Liquid 1 has different properties than Liquid 2.
The student knows that a chemical reaction has occurred because Liquids 3 and 4 have different properties than Liquids 1 and 2.
The student knows that a chemical reaction has occurred because a chemical reaction always occurs when two liquids are mixed together.
I'm not sure how to use it using the Series, but it would be the plastic comb
Explanation:
In the winter, it's likely to be cold and the glass would absorb that energy, also making it cold. in order to be able to hold it, you would need something warm, thus making the plastic one the better option as it is less likely to absorb the cold energy
