To balance the chemical equation for the reaction of chlorine gas with cold, dilute sodium hydroxide (NaOH), we can follow these steps:Step 1: Identify the Reactants and Products In this reaction, the reactants are chlorine gas
There are other ways of making Magnesium Chloride, for example by passing chlorine gas through a solution of Magnesium Hydroxide, but the ionic constituents must be present. So the equation Mg+2HCl=H2+MgCl2 is not a causal law à la Mackie. Our survey of the chemical literature showed that...

Balance any equation or reaction using this chemical equation balancer! Find out what type of reaction occured. Read our article on how to balance chemical equations or ask for help in our chat. Examples Chlorine + Fluorine = Chlorine Trifluoride Cl + F + C = CF2Cl2 Cl + F = Cl + F...
Anempirical formula consists of symbols representingelementsin acompound, such as Na forsodiumand Cl forchlorine, and subscripts indicating the relative number ofatomsof eachconstituentelement. (A subscript is not used, however, unless the number is more than one.) Thus,benzeneis represented by the...
For instance, the combustion of methane can be represented in the form of a chemical equation as shown below. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) Common Symbols Symbols can be used to differentiate between different kinds of reactions. Different types of arrows indicate different types...
always written in the left-hand side of the equation as symbols. These symbols can represent individual atoms, elements, or even compounds. The symbols used are not random; they come from the periodic table. Each element has its own Latin symbol, e.g., Sodium Na, Chlorine Cl and so on...
