Functional group
Explanation:
Functional group is specific group of atom or bond associated to an organic compound that determines the chemical properties of that compound. This atom is bonded in a certain way or specific arrangement to give the compound a peculiar physical and chemical characteristics.
Functional group like the alkyl group -CH3 is found in organic compound series like the alkane family. The chemical properties specific to the alkyl group will be active in the compound of alkane family because of the presence of the functional group Alkyl(-CH3). The functional group also plays a major role in the chemical reactivity of the compound. For example the functional group of alkyl are often non reactive, this non reactive nature will definitely rub off on the chemical properties of the compound it is attached.
Functional group like -OH is usually found in Alcohol . Due to the presence of this functional group (-OH) alcohol possess a peculiar chemical properties. The compounds possess an hydrogen bond which invariably lead to the higher boiling points of the alcohol compounds. Other functional group can be bonds like double bond found in alkene compound or triple bond found in alkyne compound.

Answers
Explanation :
As we know that the geometrical symmetry of the molecule and the polarity of the bonds both are equally important for determining the polarity of the molecule.
The molecule that has zero dipole moment that means it is a geometrical symmetric molecule and the molecule that has some dipole moment that means it is a geometrical asymmetric molecule.
As the molecule is symmetric, the dipole moment will be zero and the molecule will be non-polar.
As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.
Thus, we can say that the a symmetry molecule is non-polar in nature and an asymmetry molecule is a polar molecule.

Answers
Answer: is equal to
Explanation: According to the law of conservation of mass, mass can neither be created nor be destroyed. The mass has to be same on both sides of the reaction and to make this happen, the number of atoms of every element must be equal in reactants and products.
2 moles of hydrogen weigh=
1 mole of oxygen weigh = 32 g
Mass of reactants = 36 g
2 moles of water weigh=
Mass of products = 36 g
Thus mass of reactants = mass of products = 36 g
