Explanation:

A chemical reaction is one in which a chemical change occurs.

Based on these premise;

 Baking  cake batter is a chemical reaction because you cannot reverse the process

  Shredding a paper is not a chemical reaction because no new kind of matter is produced.

  Twisting of a metal wire is not a chemical reaction

   Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed

Car wax mostly contains beeswax and carnauba wax. These large hydrocarbons are ideal to use because they _____ water.
hichkok12 [17]
These waxes are highly hydrophobic (repellant) of water, so the correct answer would be D) repel.
