Answer : The correct option is, (1) Two H_2O_2 molecule should decomposes to form the given products.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given unbalanced chemical reaction is,

$H_2O_2\rightarrow 2H_2O+O_2$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the H_2O_2 and we get the balanced chemical equation.

The balanced chemical reaction will be,

$2H_2O_2\rightarrow 2H_2O+O_2$

Hence, the correct option is, (1) Two H_2O_2 molecule should decomposes to form the given products.

mechanics (greek is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
