Yes, the number 4 in the equation is an example of a coefficient. It represents the number of moles or molecules involved in the reaction. In this case, it indicates that 4 moles of water (H2O) are produced in the reaction.
Yes, the number 4 in the equation is an example of a coefficient. A coefficient is a number that is placed in front of a chemical formula to indicate the number of molecules or moles of each substance involved in a chemical reaction. In this case, the coefficient of 4 indicates that 4 moles of H2O (water) will be produced as a product in the reaction.
