Determine the initial energy level when an electron in a hydrogen atom transit to n sub f = 2 and emits a photon of 432nm (speed of light, c=3x10^8 , h=6.63x10^-34 , R sub h = 2.18x10^-18)

Can someone me with these questions plz.

What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
