Draw below the process used to shorten the carbon chain of a carbohydrate. Write the name of the reagents needed on the arrows to perform the sequence of reactions. What is this process called?
At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3. H2(g)+I2(g) 2HI(g) Kc=53.3 At this temperature, 0.800 mol of H2 and 0.800 mol of I2 were placed in a 1.00-L container to react. What concentration of HI is present ..
Problem- A 1.325g sample of sodium oxalate (Na2C2O4) is dissolved in dilute H2SO4 and then titrated with a KMnO4 solution. If 30.95mL of the KMnO4 solution is required to reach the equivalence point, what is the molarity of the KMnO4 solution
a gas occupies 4.04 l at 860 torr and 10c. what volume will it fill if the pressure is changed to 731 torr and the
For a radioactive decay (decomposition of a radioactive substance) the half-life is 6.0 h. How much radioactive substance remains after 22 h, in % (radioactive decay is a first-order process)
1. Explain the difference between climate change and global warming 2. Explain completely the Greenhouse Effect
At a fixed temperature, equal moles of N2 (g) and F2 (g) are mixed in a constant pressure container (the volume of the container changes in order to keep the pressure at a constant value). The N2 (g) and F2 (g) are allowed to react, producing NF3 ..
What is the net ionic equation of the reaction of FeCl2 with NoOH ? Express your answer as a chemical equation.
A particular reactant decomposes with a half-life of 115 s when its initial concentration is 0.353 M. The same reactant decomposes with a half-life of 225 s when its initial concentration is 0.180 M.

1.__________ is referred to as the graveyard of RBCs.
The standard enthalpies of formation of SO3(g), S(g) and O(g) are -359.7, +278.8 and +249.0 kJ mol-1, respectively. Use these data to calculate the average bond energy (in kJ mol-1) of the S=O double bond.
The below table lists pressure and volume measurements for air in a cylindrical piston of an air compressor. The variables may be assumed related
