the reactants should be written properly , an arrow should be put which indicates the direction of reaction , the catalyst and external factors affecting the reaction should be written on the arrow , the products should be written properly and should be balanced correctly.
What conventions are followed while writing the scientific name?
- The name of the genus begins with a capital letter.
- The name of the species begins with a small letter.
- When printed, the scientific name is given in italics.
- When written by hand, the genus name and the species name have to be underlined separately.
What are important conventions followed while writing a chemical equation?
Convention used in Writing Chemical Equations
The correct formulas of the reactants are always written on the left side of the equation . The correct formulas of the products are always written on the right side of the equation. The reactants and products are separated by an arrow pointing toward the products.
What conventions are followed Write writing the specific names?
The binomial name consists of a genus name and specific epithet. The scientific names of species are italicized. The genus name is always capitalized and is written first; the specific epithet follows the genus name and is not capitalized.
What are the rules to be followed while writing a chemical equations?
The rule for writing chemical formula is as follow: Firstly, write the symbols with positive charge valency first. Secondly, write the valency of each atom on the top of its symbol. Thirdly, divide the valency number by their highest common factor ignore the positive or negative radicle .
What is a chemical formula list some examples?

How do you write chemical symbols?
Each element is given its own chemical symbol, like H for hydrogen or O for oxygen. Chemical symbols are usually one or two letters long . Every chemical symbol starts with a capital letter, with the second letter written in lower case. For example, Mg is the correct symbol for magnesium, but mg, mG and MG are wrong.
What is the importance of scientific name?
Scientific names are informative
Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called “binomial nomenclature.” These names are important because they allow people throughout the world to communicate unambiguously about animal species .
Who is called as the father of taxonomy?
Today is the 290th anniversary of the birth of Carolus Linnaeus , the Swedish botanical taxonomist who was the first person to formulate and adhere to a uniform system for defining and naming the world’s plants and animals.
Which is the correct way to write the name of an organism?
The correct way to write a scientific name is by using the genus and species of the organism . This two-way naming system is called binomial...
What is the term taxonomy?
Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.
What is binomial nomenclature system who proposed this list four conventions that are followed while writing the scientific names?
Binomial nomenclature is the system of naming plants and animals where each organism name is denoted by two name one called the genus and the other the specific epithet. This system was given by Carolus Linnaeus .
What does binomial nomenclature include?
The scientific name of a species that is set by binomial nomenclature entails two parts: (1) generic name (genus name) and (2) specific name (or specific epithet) . In this regard, the scientific name is also referred to as the binomial name (or simply, binomial or binomen).
What are the rules of writing chemical formula Class 9?
Writing the Molecular Formula
Write the symbol of the positive ion/radical to the left and the negative ion/radical to the right along with their valency number . Interchange the valency number of the radicals and shift them to the lower side.
What are reaction types?
Basic chemical reactions can be grouped into categories based on the types of changes that are occuring during the reaction. There are five basic categories – synthesis, decomposition, combustion, single replacement, and double replacement .
