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.
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. All the reactants and products are gases (indicated by the gâs in parentheses).In this reaction, all reactants and products are invisible. The heat being evolved is the clue that tells you a reaction is taking place. This is a good example of an exothermic reaction, a reaction in which heat is given off.ll the reactants and products are gases (indicated by the gâs in parentheses). In this reaction, all reactants and products are invisible. The heat being evolved is the clue that tells you a reaction is taking place.
