The coefficients in a chemical equation tell how many molecules of that type are reacting. The arrows point in the direction of the reaction. Ex. 2 H + 1 O -> 1 H2O has two hydrogen molecules interacting with one oxygen molecule to form one water molecule.
The arrow points from the reactants towards the products so it tell us the direction in which a reaction is proceeding.
The reactants are on the tail side of the arrow and are separated by plus signs, the products are on the head side of the arrow and are also separated by plus signs.
The process of photosynthesis is a chemical change, and it can therefore be expressed in the form of a chemical equation: 6CO2 + 6H2O --> 6O2 + C6H12O6. The law of conservation of matter, which is the underlying principle of stoichiometry, tells us that glucose is in a 1:6 ratio with the other reagents in the photosynthesis reaction. In any chemical reaction equation, the number of atoms of each element must be the same on either side of the arrow.
You get the reactants, products, and the ratio that the chemicals react in. It also gives information on what processes the chemicals are undergoing, such as oxidation/reduction and acid/base.
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
A balanced equation has equal numbers of each type of atom on each side of the equation.Chemical equations usually do not come already balanced.It tells "Matter is neither created nor destroyed."Therefore, we must finish our chemical reaction with as many atoms of each element as when we started.
A chemical equation is a way of showing on paper what is happening in the laboratory or the world as chemicals interact. Here are some sentences.Our teacher made us write down the chemical equations we were going to study every day before we started class.I can't really understand this chemical equation.The chemical equation says that these chemicals should combine together.

A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.

A chemical sentence is an expression indicating the 'beginning' and 'end' products of a chemical process NaOH + HCl => NaCl + H2O + heat Unlike an equation, it is not (necessarily) reversible, so it 'travels' in the direction indicated by the arrow
it tells us about chemical reactions in our body.

The answer about SE is: symbol equation
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
It tells us how much energy is available in any given mass and of course also the reverse.
