Fructose is a sugar commonly found in fruit. A sample of fructose, C 6 H 12 O 6 , weighing 4.50 g is burned in a bomb calorimeter that contains 1.00 L of water ( d = 1.00 g / mL ) . The heat capacity of the calorimeter is 16.97 kJ/°PC. The temperature of the calorimeter and water rise from 23.49°C to 27.72°C. (a) What is q for the calorimeter? (b) What is q for water in the calorimeter? (c) What is q when 4.50 g of fructose are burned in the calorimeter? (d) What is q for the combustion of one mole of fructose?

In the solid state, oxalic acid occurs as
a dihydrate with the formula H2C2O4
C+2H2O. Use this formula to
calculate the formula weight of oxalic
acid. Use the calculated formula
weight and the number of moles
(0.00504mol)
of oxalic acid in each titrated
unknown sample recorded in Table
6.4 to calculate the number of grams
of pure oxalic acid dihydrate
contained in each titrated unknown
sample.

Consider a pair of elements with 2p and 4p valence orbitals (e.g., N and Se). Draw their
(2p and 4p AO's) radial probability plots, and sketch their angular profiles. Then, consider these
orbitals from the two atoms forming a homonuclear л-bond. Which element would have a
stronger bond, and why?
(4 points)
Write the reaction and show the mechanism of the reaction. Include the mechanism
for formation of the NO2+
2. Explain, using resonance structures, why the meta isomer is formed. Draw possible
resonance structures for ortho, meta and para.
