Define free energy, and explain how its change is calculated.
Explain the relationship between free-energy change and spontaneity of reactions.
if 1.500 g of solute that has a molar mass of 125.0 g were dissolved in 35.00 g of camphor what would be the resulting
One way of obtaining pure sodium carbonate is from side to side the decomposition of the mineral trona Na 3(CO3)(HCO3)*2H2O molar mass: 226.03 g/mol, as exposed in the subsequent reaction 2Na3(CO3)(HCO3)*2H2O(s) ----->3Na2CO3(s) + CO2(g) + 5H2O(g)..
