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.

Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.

I hope that this helps! :D

melomori [17]
Ionization energy (IE) is the amount of energy required to remove an electron.

If you observe the IEs sequentially, there is a large gap between the 2nd and 3rd. This suggests it is difficult to remove more than 2 two electrons. Elements that lose two electrons to become more stable are found in the Group 2A (2 representing the number of electrons in the outermost valence shell).
