intenzxboi said:I was wondering how come when ever there's a question like aluminum reacts with bromine it is usually written like Al + Br2? or Potassium reacts with oxygen is K + O2?
How do we know when there's 2 of them?? Is there like a special rule? Why isn't there K2 or Al2??

AlBr3 & K2O2 are though.
Chemical reactions are processes in which one or more substances are transformed into new substances with different physical and chemical properties. These reactions involve the breaking of bonds between atoms and the formation of new bonds to create new molecules.
Symbols are used in chemical reactions to represent the elements and compounds involved. This allows for a concise and standardized way of representing chemical reactions, making it easier to communicate and understand the reactions.
The numbers in chemical reactions, known as coefficients, represent the relative amounts of each substance involved in the reaction. These coefficients are used to balance the chemical equation, ensuring that the number of atoms of each element is equal on both sides.
The law of conservation of mass states that matter cannot be created or destroyed, only transformed. In chemical reactions, the total mass of the reactants is equal to the total mass of the products. This means that the number of atoms of each element must be the same on both sides of the chemical equation, as atoms cannot be created or destroyed.
Symbols and numbers can be used to write and balance a chemical equation, which can provide information on the reactants and products involved in the reaction. This allows for the prediction of the outcome of a chemical reaction, such as the formation of new substances or the release of energy.
