A flexible balloon containing 3 L of hydrogen gas at 27 °C and 101 kPa was allowed to ascend through the atmosphere. At some height in the stratosphere when the pressure was 2.1 kPa and the temperature was 2 °C, the volume of the gas in the balloon would be A.(3×27×101)/2×2.1
B.(3×300×101)/(275×2.1)
C.(3×300×2.1)/(275×101)
D.(3×275×101)/(300×2.1)

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
