Calculate the temperature change that occurs when 364 cal of heat are added to 1.39 kg of ethanol. cp for ethanol is 2.42j/g ° c

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

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
