The amount of CO2 in the atmosphere has increased dramatically due to(mainly) excessive burning of fossil fuels.
Answer:
(2) the mole ratios of the substances in the reaction
(3) the total number of electrons in the reaction
(4) the total number of elements in the reaction
The coefficients in a balanced chemical equation represent: (2) the mole ratios of the substances in the reaction.
A balanced chemical equation refers to an equation in which the number of atoms present on the reactant side (left) is the same or equal to the number of atoms present on the product side (right) of a chemical equation.
A coefficient can be defined as a number that is placed in front of a chemical symbol (formula) of an element or chemical compound in a chemical equation.
