what is chemical equation what are the necessary condition to fulfill it how it is written and balance give an example
Answers
conditions
reactant must be in the left hand side
product must be in the right hand side
and there will be an arrow mark between the reactant and the product and the catalyst if possible should be above the artow mark
Answer:
Chemical Equation:
Explanation:
The method of representing a chemical reaction with the help of symbols and formulae of the substances involved in it is known as chemical equation. For example, zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas.
Conditions necessary for chemical reactions :
- Close contact.
- Solution form.
- Heat.
- Light.
- Catalyst
Written:
In a chemical equation, the reactants are written on the left, and the products are written on the right. The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
Balance:
An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
Example:
Examples of chemical reactions in everyday life include photosynthesis, rust, baking, digestion, combustion, chemical batteries, fermentation, and washing with soap and water. Chemical reactions occur everywhere in the world around you, not just in a chemistry lab.
Representation of a chemical reaction in terms of symbols and chemical formula of the reactants and products taking part in the reaction is known as a chemical equation. For example, NH3+HCl→NH4Cl, in this reaction ammonia and hydrochloric acid is reacting to form ammonium chloride.
