Answer:
If you add the masses of all the products after fission, they are LESS than the mass of the reactants.
Explanation:
A nuclear fission reaction is a radioactive reaction which in which a heavy nucleus spontaneously disintegrates into 2 lighter nuclei and some neutrons with a release of large amount of energy.
When nuclear fission occurs, a mass deficit between the decaying nuclei and the product occurs. It is this mass that actually yields the energy that is produced as a by product of the reaction.
Answer:
The pH is 4.76 (option C)
Explanation:
pH of a solution = TO BE DETERMNED
[sodium acetate] = 1M ; [acetic acid] = 1M
K = [H+] [A-] / [HA]
K = [H+] [1] / [1]
K = H
pH = pK
⇒ now pH is equal to pK
⇒ The value of pK is given which is 4.76
⇒ This means the value of the pH is also 4.76
<span>The three methods are
wet gas desulfurisation(W)
dry gas desulfurisation(D)
seawater gas desulfurisation.(S)
In method W Calcium carbonate, CaCO3 material is used and material is obtained by quarrying. The solid waste is sold for use in buildings.
In method D Calcium oxide, CaO is used and the material is obtained by Thermal decomposition of calcium carbonate. Solid waste is sent to landfill.
In this method material is obtained from sea water. Liquid waste is returned to the sea.</span>
