In some chemical reaction, the rate at which the amount of substance changes with time is proportional to the amount present. If 100 liters of chemical substance reduces to 70 liters during the first 10 hours of the reaction, how many liters of chemical will remain after another 12 hours

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
