For the acids, use the formula pH = -log[H"). (Because HCI has 1 Htion per formula unit, [HT] equals the molarity.) For water, use what you know about the pH of neutral solutions. For the bases, examine and
extend the pattern. DONE

The speed of light is around 6.706×10^8 miles per hour. what is the speed of light in units of miles per minute?

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
