The ceiling fan direction in winter should be rotating clockwise or reverse. Warm air rises and gets trapped near the ceiling so when the ceiling fan direction is in reverse mode it circulates the warm air from the ceiling to the floor helping take the chill out of the air.
A reactant is a substance that is being used up or consumed in a chemical reaction. It is needed in large amount as compaed to reagent. A reagent is something which is used to initiate a reaction and aids to carry out it and it is also consumed in a reaction, unlikely to catalysts which are not consumed in a reaction.
Reactants and Products in Chemical Reactions. ReactantsâProducts. In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products.he 2 in front of the oxygen gas and the 2 in front of the water vapor are called the reaction coefficients. They indicate the number of each chemical species that reacts or is formed. Methane and oxygen (oxygen is a diatomic â two-atom â element) are the reactants, while carbon dioxide and water are the products.
