Problem- Calculate the standard entropy change for the decomposition of solid calcium carbonate into solid calcium oxide into solid magnesium and oxygen gas.
I am in need please provide me complete solution for the above problem so I can get right solution
The pKa of hydrochloric acid is about -6. On the basis of this information, would aqueous sodium chloride be sufficiently basic to deprotonate benzoic acid? Explain your reasongin.
The value of E for the following reaction is 0.34 V. What will the cell potential be when the [Cu2+] =10 M and the [Cr3+]=1 M? 2Cr(s) + 3 Cd 2+ (aq) --> 2Cr3+ (aq) + 3Cd(s) a)0.31 b) 0.46 c) 0.4 d) 037 e)0.28
A sealed flask contains 0.45g of water at 28 °C. The vapor pressure of water at this temperature is 28.36 mmHg. Explain what is the minimum volume of the flask in order that no liquid water is present in the flask

mixed in water and treated with 53.20 mL of 0.1030 M I2 (253.80amu) according to the equation C6H8O6 (s) + I2 (aq) ----> C6H6O6 (aq) + 2HI (aq)
A hydrocarbon is found by combustion analysis to contain 87.17% carbon and 12.83 hydrogen by mass. Determine the smallest possible molecular formula for this compound.
The ion concentration of blood is typically around 135 - 145 mM. To make 1.00 L of a solution containing 140 mM NaCl using a stock 2.00 M NaCl solution and water, how much water would you use
As well suppose that the concentration of all the other reactants are in large excess and that R is the only colored species involved. Define which function, A ln A, or !/A, would yield a strait line graph when plotted against elapsed time.
For the subsequent reactions, state the balanced formula equation, complete ionic equation and net ionic equation. If no precipitate forms, write "No reaction."
