Consider a metal atom, which we will give the symbol M. Metal M can readily form the M+cation. If the sphere on the left below represents the metal atom M, which of the other three spheres would probably represent the M+ cation? Explain your choice.
Calculate the equilibrium constant, K. (e) Which side of the reaction (reactants or products or neither) is favored structurally?
This was a question on my Mastering Chemistry homework. It's from Tro's Cha: Determine the pH of the following two-component solution: 0.260 M NH4NO3 and 0.102 M HCN
when electrons move from the fourth energy level to the second energy level, they emit visible light. explain why the light emitted when an electron makes this move in a sodium atom is a different color than the light emitted
