An electron in the hydrogen atom makes a transition from an energy state of principle quantum number n to the n=1 state. If the photon emitted has a wavelength of 95nm, what is the value of n?
On this problem I tried using the equation 1/wavelength = R (1/n^2 - 1/n^2)= 1/ (9.5x10^8m) = 1.097x10^7 m^-1 (1/1 - 1/n^2)
what volume of 3m sulphuric acid is required to neutralize all of the c7h5nao3 and the excess sodium hydroxide present
A mixture of fuel containing 0.530 mol CH4/mol, 0.330 mol C3H8/mol, and 0.140 mol C5H12/mol at 60.0°C and 125 kPa (gauge) enters a furnace at a rate of 91.0 L/min where it reacts with 17.4% excess air.
NaOH(aq) is rapidly mixed with an equal volume of 0.020 mol L^-1 HCN(aq). Calculate the time, in seconds, required for this [OH] to decrease to 1.0×10^4 mol L^1. (Hint: Start from the rate law in the form Rate = k [HCN ]^n[OH]^m.
