Equations \(\ref{3.1.1}\) and \(\ref{3.1.2}\) are balanced chemical equations. What is different on each side of the equation is how the atoms are arranged to make molecules or ions. A chemical reaction represents a change in the distribution of atoms, but not in the number of atoms.

28 Απρ 2024 · Chemical formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's molecular formula cannot be reduced any more, then the empirical formula is the same as the chemical formula.
Chemical formulae, equations and calculations. Chemical equations use an element’s symbol, rather than writing out its full name. On this page we’ll learn how to write symbol equations as well as how to calculate the number of moles of a substance.

A chemical reaction is the process by which one or more substances are changed into one or more new substances. Chemical reactions are represented by chemical equations. Chemical equations have reactants on the left, an arrow that is read as "yields", and the products on the right.
Chemists use symbols and formulae to represent elements, ions and compounds. Word equations and balanced chemical equations model the changes that happen in chemical reactions.
