The volume of a sample of H2 gas was decreased from 14.81 to 2.63 L. If the final pressure exerted by the H2 sample was 311.7 kPa, what pressure did the H2 exert before its volume was decreased? kPa

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
