Chapter 3, Problem 101QRT
Boron forms an extensive series of compounds with hydrogen, all with the general formula BxHy. To analyze one of these compounds, you burn it in air and isolate the boron in the form of B2O3 and the hydrogen in the form of water. You find that 0.1482 g BxHy gives 0.4221 g B2O3 when burned in excess O2. Determine the empirical I formula of BxHy.

Don't used Ai solution
The standard Gibbs energies of formation of CaO(s), CaCO3 (calcite), and CO2 (g) are
-604.04, -1128.80, and -394.37 kJ/mol, respectively. Find the value of AG, and Keq for the
following reaction:
CaCO3 CaO (s) + CO2 (g)
[ap
A dry mixture containing 1 g of each solid [CaCO3(s) and CaO(s)] is on the lab bench in
contact with the atmosphere, which contains a partial pressure of 10-35 bar CO2 (g). What is
the total Gibbs free energy of the system containing all three species before any reaction has
happened? Does the equilibrium driving force favor conversion of one of the solids into the
other, or are the solids equilibrated with one another?
