Molecularity
Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular reaction, a single molecule sh..

Molecular Mass
12 is the molecular mass of carbon The molecular mass of a substance is the relative mass of its molecule as compared with the mass of a 12 C atom taken as 12-units. It indicates the number of times; one molecule of the substance is heavier than at..
Molecular Formula
The formula that gives the symbolic representation of the actual number of atoms of various elements present in one molecule of the compound is called the molecular formula. Discrete molecules can be described by this formula. As it represents one molecule of the substance giving the nam..
Molecular substances
Molecular substance having nearly spherical molecules have closed packed arrangements. Examples: Solid H 2 has hcp structure, while solid CH 4 , HCl, H 2 S have ccp structu..
Molecular mass
The molecular mass of a substance is the relative mass of its molecule as compared with the mass of a 1 2 C atom taken as 12-units. It indicates the number of times, one molecule of the substance ..
Molecular reactions
The reactions between covalent compounds occur between their molecules. These involve the breaking of covalent bonds in reacting molecules and forming new covalent bonds to give molecules of the products. These reactions are quite slow because energy is required to break covalent bond..
Relationship between Gram Molecular Weight and Gram Molecular Volume
Gram molecular weight (GMW) is the relative molecular mass of a substance expressed in grams. It is also called gram molecule of that elemen..

Tutors are very patient to explain me the same problem again and again until i understand...Really helpful...Thank you all...
I used to fail in my math class, after I joined Tutor Vista I am getting good grades in math, Thank you
For every concept, here we get explanation along diagrams, I really liked it very much
Their whiteboard is great. Online tutoring from this site is as good as like face to face tutoring and the great thing is I dont have to spend a lot.
