Two of the emission wavelengths in the hydrogen emission spectrum are 410 nm and 434 nm. one of these is due to the n=6 to n=2 transition, and one is due to the n=5 to n=2 transition. which wavelength goes with which transition and why?

What produces wave a)sound b) heats c)transfer of energy d)vibrations

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )

How does the value of the equilibrium constant show that a reaction reaches equilibrium very quickly? (a) the equilibrium constant is large. (b) the equilibrium constant is small. (c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
