Word equations can be very useful, but do have one major drawback. They cannot be used for any quantitative work. A word equation does not tell how many moles of each material are needed or how many moles of product are formed.
What are the advantages and disadvantages of chemical equation?
ADVANTAGE-Chemical Reactions helps us to find new products which can be useful for future inventions in a great way. DISADVANTAGE-Chemical Reactions cost us a lot of time and money for buying various chemicals and their instruments and sometimes harmful product may be produced which may harm us and our environment.
Why is it important to write chemical equations instead of word equations?
In chemistry, a word equation indicates the order of events of a chemical reaction. The number of moles and types of reactants yield the number of moles and types of products. Word equations help in learning chemistry because they reinforce the thought process involved in writing a chemical reaction or equation.
What are four limitations of chemical equation?
Energy is always required to drive a chemical reaction.
What are the advantages of using chemical equation?
A balanced reaction gives the proportion of reactants and products; so when you don’t want to waste reactants (and this is very important if you are a factory owner not wanting to waste your profits); you can use these proportions to measure out the exact quantity of reactants.
What are the disadvantages of chemical?
List of Disadvantages of Chemical Energy
- It can be harmful to the environment.
- It comes with a high cost.
- It can produce radioactive waste.
- It is non-renewable.
- It is not good for human health.
What are the disadvantages of chemical reactions?
List of the Disadvantages of Chemical Energy
- The primary way to obtain chemical energy is through a combustive process.
- Chemical energy can be harmful to the environment.
- It is impossible to replace an expended chemical energy resource.
- Chemical energy isn’t always the cheapest option.
Is word equation is a balanced chemical equation?
Answer: Formula of a reactant or product cannot be altered, but chemical equation is balanced by multiplying the reactant or product with numbers like 2,3,4,5 and so on to balance the number of atoms in the chemical equation.
What does a chemical equation show that a word equation does not?
Unlike in a math equation, a chemical equation does not use an equal sign. Instead the arrow is called a yield sign and so the equation is described as reactants yield products.
What are the advantages of naming and writing chemical formula?
Chemical Nomenclature is important because it ensure that a spoken or written chemical name leaves no uncertainty concerning which chemical compound the name refers to: each chemical name should refer to a single substance.
What are the limitations of a chemical equation any 3?
(ii) It does not tell us the actual concentration or dilution of the reactants used in the reaction. (iii) It does not tell whether the reaction starts at its own or some heat is required to start the reaction. (iv) It does not tell whether the reaction is violent in nature or not.
What are the disadvantages associated with hit and trial method of balancing the equation?
The disadvantages of hit and trial method of balancing the equations are: The method takes a lot of time and is very tedious. It becomes difficult to balance the reaction that contains same element repeated in number of compounds. Any information about the mechanism of the reaction is not obtained.
What are limitation of a balanced chemical equation?
1. The balanced chemical equation does not give the actual yield of the product. 2. The balanced chemical equation does not give the information about the rate of the chemical reaction.
What are the advantages of using a chemical equation for the representation of a chemical reaction Why is it necessary to balance a chemical equation?
Answer: Chemical reaction is just a rearrangement of atoms. It can neither create nor destroyed during the course of a chemical reaction. Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system.
What are some disadvantages of chemical energy?
What Are the Disadvantages of Chemical Energy?
- It isn’t a sustainable form of energy.
- It can be expensive.
- Some forms of chemical energy are quite rare.
- It can produce harmful waste.
- It can be used to create devastating weapons.
- It offers short-term benefits for long-term consequences.
What are some of the disadvantages of studying chemistry?
Chemists frequently have to work long hours under deadlines, potentially creating job stress. A distinct disadvantage of chemistry careers is the risk of exposure to chemicals such as acids, biological agents, volatile organic compounds and compressed gasses.
What are the disadvantages of common chemicals used on earth?
On the other hand, the disadvantages to widespread pesticide use are significant. They include domestic animal contaminations and deaths, loss of natural antagonists to pests, pesticide resistance, Honeybee and pollination decline, losses to adjacent crops, fishery and bird losses, and contamination of groundwater.
What are the advantages and disadvantages of chemical industries?

- economic boom n latest techonology.
- less poverty.
- more development.
- more jobs for people.
- increase in exports which will make large profits n will be utilized in the development of country.
- GDP per capita will increase.

What are the disadvantages of using chemicals in agriculture?
Disadvantage: Unsustainable Soil Conditions
Nitrogen is often regarded as a highly effective and cheap fertilizer. However, repeated use of the chemical can cause an imbalance in the pH of the soil, eventually rendering it useless for growth of any kind.
What are the disadvantages of chemical fertilizers?
Disadvantages:
- Chemical fertilizers affect micro-organisms living in the soil.
- Chemical fertilizers are highly soluble in water hence they leach away into groundwater without fully benefiting the plant.
- Chemical fertilizers encourage plant disease.
Whats a word equation?
A word equation represents a chemical reaction using the names of the substances involved. Word equations do not show any chemical symbols or formulae.
