John takes 3 hours longer than Andrew to peel 500 lb of apples. If together they can peel 500 lb of apples in 8 hours, then how longer would it take each one working alone?
Substitution and elimination reactions are competing reactions. Under what conditions can you ensure that substitution will predominate
water can be expressed in polynomial form, vs the number of moles of ethanol (nEtOH), as 1002.93+54.6664*nEthOH-0.36394*nEthOH^2+0.028256*nEtOH^3, the partial molar volume of ethanol has its minimum value at m > 0.004 mol/kg.
