Some [basic concepts] of chemistry class 11 questions and answers with numerical’s and formulas

Today in this article we will learn some basic concepts of the chemistry of class 11 including formulas to solve numerical’s along with questions and answers.

Some basic concepts of chemistry questions

Chemistry is the branch of science that studies the composition, properties, and interaction of matter.

Chemistry plays a central role in science and is often convoluted with other branches of science like physics, biology, and some part of basic science, etc. Chemistry also plays an important role in daily life.

Scientists who work in the chemistry field are also known as chemists that are a part of the discovery of medicine that treats disease.

Some basic concepts of chemistry of class 11 numericals

formula for molarity = Number of Moles/Volume in Litre

Number of atoms = Moles * NA

Number of moles = weight/molecular weight

Volume of solution = Mass/Density

Molality = (moles of solute/weight of solvent) * 1000

Mole fraction = No.of Moles of component / Total no.of moles

How do I start basic chemistry?

Basic Chemistry is a study of matter basically that deals with a detailed study of the structure of atoms and molecules and the quantitative relationship between the mass and the number of these particles.

The constituent particles of matter that exists in three states i.e solid, liquid, and gaseous their studies also are the part of basic concepts of chemistry.

Q1. What is Chemistry?

Ans: Chemistry is a branch of science that deals with the study of properties of matter their composition and interaction of matter.

Q2. What do mean by molecular formulae?

Ans: A chemical formula that gives the total number of atoms of each element in each molecule of a substance.

Q3. What is a chemical bond?

Ans: A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.
