1. A 50g block of aluminum at-100°C is submerged in 30g of water at 20°C. Cwater = 4.184 J/gºC
CA = 0.89 J/gºC
AHrus water = 334 J/g
a. What is the final temperature of both substances?
b. How much energy is gained by the block of aluminum?

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
