A 10.00 g sample of TNT (213 g/mol) is burned in a bomb calorimeter with a heat capacity of 420 J/ºC. The calorimeter contained 610 grams of water (4.18 J/gºC) and the temperature of the water was measured to go from 20.00 ºC to 24.08 ºC.  Based on this data, what is the heat of combustion per mole of TNT?

Calculate the enthalpy change for the reaction, NO(g)  +  O(g)  →  NO2(g) from the following data: NO(g) +  O3(g)  → NO2(g)  +  O2(g)     ΔH = –198.9 kJ                 O3(g)   →  1.5 O2(g)                ΔH = –142.3 kJ                O2(g)   →    2 O(g)                   ΔH =  495.0 kJ

A gas consists of 85.63 % carbon and 14.37 % hydrogen, by weight. A sample of this gas weighing 1.153 g occupies 820 mL at a pressure of 730.0 mmHg and a temperature of 77°C. Calculate its empirical and molecular formulas.

  Three different PCR reactions using a primer set with a perfect Tm of 50 C were performed. The expected product of each PCR was 1000 bp. The products obtained in each separate reaction were analyzed by electrophoresis. The results observed in the gel are depicted in the Figure. Which of the thermocycler programs described below was more likely used to obtain the results observed in Line 2; Line 3 and Line 4. The line 1 correspond to the molecular weight marker.  

The plasmid in the figure below should be transformed into a linear molecule. Which restriction enzyme can do this work? The blue lines represent target sequences for the enzymes as indicated on the map.
