In a chemical reaction, bonds between atoms are broken and new bonds are formed to produce new substances.

Atoms of one element do not change into those of another element during a chemical reaction.

Including physical states enhances the informativeness of a chemical equation by providing insights into the phases of reactants and products involved in the reaction. This helps in understanding the reaction’s stoichiometry, energetics, and practical considerations related to carrying out the ...

Mentioning the physical states of reactants and products provides additional information about the conditions under which the reaction occurs and the state in which each substance exists. This information can be crucial for understanding the reaction’s behavior and predicting its ...

Physical states such as gaseous, liquid, aqueous, and solid states of reactants and products are represented using specific notations. (e.g., (g) for gas, (l) for liquid, (aq) for aqueous solution, and (s) for solid).

The hit-and-trial method is used to balance chemical equations by making trials with different coefficients to ensure that the numbers of atoms of elements on both sides of the equation are equal, thereby achieving balance.

To balance a chemical equation, coefficients are adjusted in front of the chemical formulas of reactants and products. These coefficients represent the relative amounts of each substance involved in the reaction and are adjusted to ensure that the number of ...

It is important for a chemical equation to be balanced because an unbalanced equation violates the law of conservation of mass. A balanced equation ensures that the number of atoms of each element is the same on both sides of ...

The law of conservation of mass implies that the number of atoms of each element remains the same before and after a chemical reaction.

The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. The total mass of the elements present in the products of a chemical reaction must be equal to the total mass ...
