When Cr2+ is linked with a strong–field ligand to produce an octahedral complex, the ion has two unpaired electrons. When it is linked with a weak–field ligand, the ion has four unpaired electrons. In contrast, the complex resulting from Cr3+ always has three unpaired electrons regardless of the nature of the ligand. Explain.

The interval volume of a calorimeter is 1.12L. 1.863 g of nonae was addedas well as O2 until the pessure reached 10.0 atmand temp 23.1C. What is the full balnce equation of the combustion, how many moles of O2 are present before combustion? Once nonane was compltetly consumed, how many grams of water would be formed?
