Ethylene glycol has a specific heat of 0.578cal/(g x celcius). If 23.2g of ethylene glycol absorbs 75.6 cal of heat energy, what will the temperture increase be?

under normal conditions, which of the following would have the highest enthropy? Steam, liquid, ice, or solid chloride

which of the following substance is not a good oxidizing agent? Hydrogen peroxide, sodium hypochlorite, chlorine, ozone, or sodium metal

75.6 / (0.578 * 23.2) = 5.64 celcius
