Suppose that 2.00mL of isopently alcohol was reacted with excess acetic acid and that 2.00g of isopentyl acetate was obtained as product. Calculate the percentage yield.
solution containing 1.543g Cu(NO3)2 to reduce any copper ions present. What mass of copper was reduced in this process?
Drinking water in the USA cannot exceed 0.5 ppm mercury. What mass of mercury is present in 1.3 L of water at this concentration. What is the molar concentration of mercury
The standard cell potential for the reaction below is +0.63 V. The cell potential for this reaction is __________ V when Zn2+ = 3.5M and Pb2+ = 2.0x10^-4 M. Pb2+ (aq) + Zn (s) --> Zn2+ (aq) + Pb(s)
Consider the following equilibrium process at 686°C: CO2(g) + H2(g) CO(g) + H2O(g) The equilibrium concentrations of the reacting species are [CO] = 0.050 M, [H2] = 0.045 M, [CO2] = 0.086 M, and [H2O] = 0.040 M.
The unit of S was the J/(mol*K) the book said. But, in delta S, why the unit is J/K? I just think when I want to calculate delta S, sum of products's S - sum of reactants's S, so the unit of delta S is same as S I thought. What is it
