An approach limit at a distance from an exposed energized electrical conductor or circuit part within which a shock hazard exists
1.there is an increased likelihood of electric shock, due to electrical arc-over combined with inadvertent movement
2.when an arc flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm2 (5 j/cm2)

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
