how many of the alcohol and ethers stereoisomers of formula C5H12O have charity centers.
calculate the heat in joules released by the dissolving salt. Assume that the specific heat of the solution is the same as thar of pure water(4.184J/g- celcius) and that the calorimeter is perfect.
At 600 degrees C, the equilibrium constant for the reaction 2HgO(s) --> 2Hg (l) +O2 (g) is 2.8. Calculate the equilibrium constant for the reaction 1/2O2(g) + Hg(l) --> HgO (s)
When the following reaction is balanced in basic solution using the lowest possible whole number coefficients, the coefficient of H2O will be: CN-(aq) + MnO4-(aq) --> CNO-(aq) + MnO2(s)
