Answer:
Explanation:
The change in internal energy is given by the following expression:
Extra stability for an atom means to gain electrons to become stable .example:Cl it has 17 electrons by gaining 1 electron it achieve 18 electrons means it has octet configuration in it valency shell.Now it is stable
The equilibrium constant, Kc, can be determined knowing that the balanced chemical reaction is N2 + 3H2 = 2 NH3. At equilibrium, Kc is equal to (concentration of NH3)^2 / [(concentration of N2) x (concentration of H2)^3]. Using the given values, Kc is computed to be equal to 1.9977 x 10^-4.
Plants or algae, they are herbivores
Nickel and manganese in steel add to its tensile strength and make the austenite form of the iron-carbon solution more stable, chromium increases hardness and melting temperature, and vanadium also increases hardness while making it less prone to metal fatigue. ... The inclusion of carbon in alpha iron is called ferrite.
