2 moléculas de clorato de potasio (KClO3) forman 2 moléculas de cloruro de potasio (KCl) y 3 moléculas de oxígeno (O2

The complete question is as follows: 2 molecules of potassium chlorate (KClO3) form 2 molecules of potassium chloride (KCl) and 3 molecules of oxygen (O2). Write a balanced equation for this reaction?

The balanced chemical equation is .

Explanation:

A balanced equation is defined as the equation which contains same number of atoms on both reactant and product side when a chemical reaction occurs.

Hence, when 2 molecules of potassium chlorate form 2 molecules of potassium chloride (KCl) and 3 molecules of oxygen then its balanced equation will be as follows.

Here, number of atoms on the reactant side as as follows.

Number of atoms on the product side are as follows.

Since, the number of atoms on reactant side are equal to the number of atoms on product side. So, this reaction equation is balanced.

Thus, we can conclude that the balanced chemical equation is .

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
