Answer only the one question below. This is about a labwork in chemistry, i need your help. These are the solute to be dissoolve in water and vegetable oil: Acetic acid (vinegar) Sucrose (sugar) Monosodium glutamate (vetsin) Cellulose (cotton fiber) Isopropyl or ethyl alcohol Fatty acid salts (soap) Kerosene Naphthalene balls (NOTE: So this 10 will be mixed with water and vegetable oil) Question: 1. What do you think is the main difference of the outcome of the solution of those who are mixed with water and those who are mixed the mixed with vegetable oil? Please show the difference and similaries(if theres any).
