Problem- What limitations have you or someone you know encountered in the past in using nonrelational structures (such as in a Microsoft® Excel® or Word file) to store data? What were the advantages?
Describe the solution of above problem
When 5.00g of LiCl is added to 100g of water the temperature of the water was found to increase by 9.94*C. Calculate the molar enthalpy of solution for LiCl. Assume the specific heat of the mixture is 4.18 J/g*C.
What percentage, by volume, is needed of ethylene gylcol in an ethylene gylcol-water mixture to keep the coolant in your radiator from freezing at a temperature of -20F
1. 1.25 moles of nocl were placed in a 2.50 l reactionchamber at 427ordmc. after equilibrium was reached 1.10 moles of
5H2C2O4(aq) + 2KMnO4(aq) + 3H2SO4(aq) ---> 10CO2(g) + 2MnSO4(aq) + K2SO4(aq) + 8H2O(l). What is the concentraton of KMnO4 solution if 22.35mL reacts with 0.5170g of oxalic acid.
Calculating Kc, Given the amount of reactant in grams in a container at a temperature and amount produced in moles, calculate Kc:
