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.

Examples of Reactants. A general reaction may be given by the equation: A + B â C. In this example, A and B are the reactants and C is the product. There do not have to be multiple reactants in a reaction, however. In a decomposition reaction, such as: C â A + B. C is the reactant, while A and B are the products. You can tell the reactants because they are at the tail of the arrow, which points toward the products. H2 (hydrogen gas) and O2 (oxygen gas) are reactants in the reaction that forms liquid water: 2 H2(g) + O2(g) â 2 H2O(l).
