The following balanced equation shows the decomposition of water (H2O). According to the equation, how many oxygen atoms are in
2 answers:
<u>Answer:</u> There are 2 oxygen atoms on the reactant side.
<u>Explanation:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form.
This law also means that total number of individual atoms on the reactant side will always be equal to the total number of individual atoms on the product side.
The given balanced chemical equation follows:
<u>On reactant side:</u>
Number of hydrogen atoms = 4
Number of oxygen atoms = 2
<u>On product side:</u>
Number of hydrogen atoms = 4
Number of oxygen atoms = 2
Hence, the number of oxygen atoms on the reactant side is equal to 2.

Answer:
The concentration of the solution is 1.364 molar.
Explanation:
Volume of perchloric acid = 29.1 mL
Mass of the solution = m
Density of the solution = 1.67 g/mL
Percentage of perchloric acid in 48.597 solution :70.5 %
Mass of perchloric acid in 48.597 solution :
=
Moles of perchloric acid =
In 29.1 mL of solution water is added and volume was changed to 250 mL.
So, volume of the final solution = 250 mL = 0.250 L (1 mL = 0.001 L)
The concentration of the solution is 1.364 molar.
