Equation definition, the act of equating or making equal; equalization: the symbolic equation of darkness with death. In an actual chemical equation, reactants are denoted by their chemical formula.

Chemical reaction definition is - a chemical change that occurs when two or more substances combine to form a new substance. Horia Varlan/CC-BY 2.0 Coefficients are the numbers placed before the reactants in a chemical equation so that the number of atoms in the products on the right side of the equation are equal to the number of atoms in the reactants on the left side.

Chemical reactions occur because of synapses.

From Wikibooks, ... Each species in a chemical equation is written: E is the chemical symbol for the element, x is the number of atoms of that element in the species, y is the charge (if it is an ion) and (s) is the physical state. This is the balancing of the equation. Let us consider an actual chemical reaction between Methane(CH₄) and Oxygen (O 2), the number of atoms on both sides must be equal. They also make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities. Emotions are typically measured in physiological responses, such as a pounding heart, sweating, blood rushing to the face, and the release of adrenaline. In order to assure the law of conservation of mass, a chemical equation must be balanced i.e. Bases are chemical compounds that, in solution, are soapy to the touch and turn red vegetable dyes blue.

Acids are chemical compounds that show, in water solution, a sharp taste, a corrosive action on metals, and the ability to turn certain blue vegetable dyes red.

Synapses are parts of the nervous system, and it is through these that neurons are able to transmit messages using neurotransmitters.
