Which conversion factor do you use first to calculate the number of grams of FeCl3 produced by the reaction of 30.3 g of Fe with C12? (What would be your first step in the bracket/train tracks?)
2Fe + 3Cl2 --> 2FeC
1 mol Fe
55.845 g Fe
3 mol Cl,
2 mol Fe
35.453 g CL
1 g Fe
162.2 g FeCl2
2 mol FeCl3

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
