What is the volume of CO2 (acting as an ideal gas) if 64.0 mL of 1.261 M HCl reacts with excess CaCO3 at 28 °C and 0.987 atm? Show your work and box your answer
2HCl + CaCO3 + H2O + CO2 + CaCl2

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
