Add all the elements together
Subtract the total amount of elements from the products
A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
a formula equation
a symbol equation if you are at school could give you a higher levele or grade bit also the symbol equation s the quicker way then writing out the the words like mg+o = magnesium oxide it is the quicker way
2NaCl + F2 -> 2NaF + Cl2 The first F in the equation has 2, so the second has to have 2 as well. But placing a 2 before the NaF, gives the Na 2. So add a 2 before the NaCl. and the Cl after the yield sign already has 2.
Heat will be on the product side of the equation, but it is not a "product" in the same sense as the chemical symbol(s) and/or formula(s) written on this side of the equation, because heat is not a tangible substance but rather an increase in the energy of nearby substances.
Chemists keep track of substances used and created in a chemical reaction by writing a balanced chemical equation. This equation accounts for the reactants (substances used) and products (substances created) in terms of their chemical formulas and stoichiometry. Balancing the equation ensures that the law of conservation of mass is obeyed.
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
The first step in writing a net ionic equation is to write down the balanced chemical equation for the reaction. From there, you can identify the aqueous ionic compounds and break them down into their respective ions. The net ionic equation will only include the ions that participate in the reaction.
Catalysts are not consumed in a reaction, so they are not considered reactants or products in the balanced chemical equation. Including catalysts in the equation can make it cluttered and unnecessary, as they only influence the rate of the reaction but are not chemically changed by the process.

Putting a chemical equation into words helps to describe the reactants, products, and the chemical reaction that is occurring. It allows for easier communication of the reaction process and helps in understanding the stoichiometry involved. Additionally, writing chemical equations in words helps to identify the type of reaction taking place.
Writing out a chemical equation for a specific chemical reaction.
:A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.An equation is balanced by changing coefficients in a somewhat trial-and-error fashion. It is important to note that only the coefficients can be changed, NEVER a subscript.
It is one way of representing a chemical reaction: it tells you what reacts and what is produced. Word equations are an efficient way to describe chemical changes, to help chemists recognize patterns, and to predict the products of a chemical reaction.

Reacting mass calculations involve determining the amounts of reactants needed to produce a certain amount of product in a chemical reaction. Start by writing a balanced chemical equation and converting the given mass of one reactant to moles. Use the mole ratio from the balanced equation to calculate the moles of the other reactant needed. Finally, convert the moles of the second reactant to mass if required.
