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 reaction, a reaction in which heat is given off. A lot of reactions are exothermic. Some reactions, however, absorb energy rather than release it. These reactions are called reactions.

Also we've recently released the Nitrate Absorbance Module designed to detect inorganic nitrate and nitrite using the standard reactive nitrate/nitrite method adapted from Strickland and Parsons, "A Practical Handbook of Seawater Analysis".
You can read the equation like this: One molecule of methane gas reacts with two molecules of oxygen gas to form one molecule of carbon dioxide gas and two molecules of water vapor. The in front of the oxygen gas and the in front of the water vapor are called the reaction . They indicate the number of each chemical species that reacts or is formed.
