Your fan should blow up in the winter. The idea is to move the heat up to the ceiling and down the walls to give the room even heat. Hot air rises so your ceiling fan needs tâ¦o blow the air from the ceiling to the floor.
It is read from left to right. The reactants are on the left side of the equation and the products are on the right side of the equation. Or in descriptive terms: The reactants are what you have at first, and products are what you have after the chemical reaction has occurred.Source(s): Engineering major.Andrew Â· 7 years ago.he reactants are on the left side of the equation and the products are on the right side of the equation.

Chemical reactions produce new substances with new properties. The starting materials in a chemical reaction are called reactants while the materials that are formed are called products. When we write an equation we put an arrow in the middle between the reactants and the products; this arrow is read as yields.he starting materials in a chemical reaction are called reactants while the materials that are formed are called products.
