The 2 in front of the oxygen gas and the 2 in front of the water vapor areed the reaction coefficients. They indicate the number of each chemical species that reacts or is formed. Methane and oxygen oxygen is a diatomic two-atom element are the reactants, while carbon dioxide and water are the products..
All the reactants and products are gases indicated by the g's 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. A lot of reactions are exothermic..Reactants and products in chemical reactions and the relationship between reactants and products..The reactants are what you start with and the products are the result. In the chemical reaction equation the reactants are on the left and the products are on the right. Product is what you get at the end of the reaction. For the example above, the 2 elements reacted, leaving behind Magnesium oxide .Reactants And Products. Showing top 8 worksheets in the category - Reactants And Products.
