C= 2,8 mol H2 =3,amol
3C(s) + 3H2(g) —>CH4(g) + HC = CH(g) ΔΗ= 310 kJ
CH4=? mol
HC = CH = ? moll
How to find the mol of
CH4 and HC=CH?

Explain what happens at the saturation point when adding salt to water at room temperature.

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
