Calcium oxide chemical formula is CaO and its molar mass in 56.0774 g mol-1.
That protons are positive charges and are equal to the amount of neutrons.
Explanation:
Since, the given reaction is
Sum of masses on both reactant and product side is as follows.
235.043924 + 1.008665 = 139.921620 + 93.915367 + (2 × 1.008665)
= 0.198272 u
As it is known that relation between energy and mass is as follows.
Energy produced =
Since, 1 u = 931.494 MeV/. Putting this value into the above formula as follows.
Energy produced =
=
= 184.69 MeV
As 1 MeV equals joules.
Hence, 184.69 MeV will be converted into joules as follows.
= J
= J
Thus, we can conclude that energy released in this reaction is J.
Answer:
Explanation:
To neutralize a chemical to a pH of 7 before discarding, one would require a significant amount of acids or bases. Our best guess is that the solution in itself is either an acid or a base. Neutralization with the right amount of a proper reagent can bring the pH of the solution to a neutral 7.
If the solution has a pH originally greater than 7, add a corresponding amount of acid to it. This will reduce the concentration and bring it to a neutral point. Provided one is dealing with a solution of pH less than 7, simply add a base to to bring the solution to neutrality.
