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.

1 A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. 2  In a chemical reaction, the atoms and molecules that interact with each other are called reactants. 3  In a chemical reaction, the atoms and molecules produced by the reaction are called products. Draw an arrow after the second oxygen molecule to show that a chemical reaction is taking place. 2  Rearrange the atoms in the reactants to make the molecules in the products on the right side of the arrow. 3  Write the chemical formula under each molecule of the products. 4  Also draw a + sign between the products.
