The minimum amount of energy required to move most loosely bound electron of a isolated neutral gas atom or molecule
False, a physical change means that the property of matter will change size, shape, color, or density. These are all examples of physical change.
A molecule consists of group of atoms that are bonded together by chemical bond. It is the smallest particle of an element or a compound that has the properties of the element or the compound embedded in it. The atoms present in one element easily forms a bonding with the atoms of another element to form molecules. The size and complex nature of molecules varies hugely. Some molecules can have a single atom as is the case with helium, while in several other elements the number of atoms in the molecule can be more than one.
only reactants are present
If equllibrium constant is greater than 10^3 then product
predominates
If equllibrium constant is greater than 10^ -3 then reactant predominates
in between 10^3 and 10^-3 the reaction is in equllibrium
and we see that the above value is 10^-31, it is very small so the answer is reactants are presents
