Answer:

so A

Explanation:

balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error

Answer:

D

Explanation:

KClO3 ==> KCl + O2

         1  K  1

         1  Cl  1

         3  O  2

There are a different amount of oxygen atoms so this equation is not balanced

KClO3 ==> 3KCl + O2

        1  K  3

        1  Cl 3

         3 O 2

None of the elements have the same number of atoms on either side of the equation therefore this equation is not balanced.

2KClO3 ==> KCl + 3O2

          2  K   1

          2  Cl  1

          6  O   6

The number of potassium atoms and chlorine atoms is different on both sides of the equation therefore this equation is not balanced.

2KClO3 ==> 2KCl + 3O2

          2  K   2

          2  Cl  2

          6  O   6

The number of atoms of each element are the same on both sides therefore this equation is balanced.

Hello! Please Answer this chemistry question!<br> Are two atoms of the same element identical?
nalin [4]

Yes they are

According to definition of an element

  • An element is a combination of one kind of many atoms into one place .

An element consists of several atoms of one type

So they are identical
