Answer:
Is about 0.53 angstroms
Explanation:
The "size" of an atom in this definition is related with the nucleus size plus the cloud of electrons that surround the nucleus, in this case, since the Hydrogen in its basic state has only one electron, practically the size of the nucleus is the size of the atom, that is 0.53 angstroms or 5.3 x 10 -11 meters.
Hope this info is useful.
The molar mass of Fe would be 55.8450.
Answer: Your friend is incorrect.
Explanation: If we have an object or something that isn’t moving, (let’s say a notebook on a desk). If there is change, and the notebook moves, there is acceleration. Force = Mass times acceleration, f = m*a. There has to be a force, first of all. If you touched the notebook and moved it, some of your energy is transferred and now the notebook has kinetic energy. If our system is you and the notebook, the total energy doesn’t change. the energy is transferred, but doesn’t change. Your friend is not correct. Please give brainliest hope this helped!
Due to <span>succinic anhydride is cyclic 5 membered anhydride which is stable compared to acetic anhydride which is open chain anhydride. hence equilibrium favors one side towards succinic anhydride.
Also: </span><span>Since, acetic acid is stronger acid than succinic acid, it will form its salt rather than succinic acid</span>
