what. is. similarities. between. heat. and. light
Answers
Answer:
Explanation:
Chemical equations describe the change of one chemical to another due to its tendency to react when mixed with another chemical or its own decomposition by heat or light. This equation uses a chemical symbol to indicate what happens in a chemical reaction.
The first ingredient used in a reaction is known as a reactant and the resulting substance is known as a product. In the chemical equation, each of the ingredients involved is represented by its chemical formula with all the reactants listed on the left and the results on the right. This material is separated from each other by an arrow pointing towards the result (reactant → result). If there is more than one reactant or product in a reaction then the compound is separated by a plus (+) sign.
For example, zinc powder (Zn) is heated together with sulfur powder (S), white zinc sulfide (ZnS) powder is produced. These reactions can be represented by the following chemical equations:
Zn (p) + S (p) → ZnS (p)
The letters in parentheses indicate the state of the compound during the reaction; solid (p), liquid (ce), gas (g) and aqueous (ak).
Another example of a balanced equation for the reaction between hydrogen gas and oxygen gas is 2H2 (g) + O2 (g) → 2H2O (ce).
