1. In 2 sentences explain the buffer system (that is , the bloods equilibrium reaction)?
2. Use le chatelier principle to explain why the buffer prevents large changes from occurring in pH when (a) an acid enters the blood stream (b) and base enters the bloodstream.
3. Explain why some types of acidosis can be treated with intravenous bicarbonate ions.
Draw the structures of the bases in DNA and indicate the H bonding interactions between the base pairs.
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the AU3+ and Li+ ions are unreactive during the titration, determine the mass percent of LiCLO in the sample.
Instead of 6 M NaOH being added to the test solution, 6 M HCl is added. How will this affect the test for the presence of ammonium ion in the solution? Explain.
What mass of melamine, C3N3(NH2)3 will be obtained from 178.5 kg of urea, Co(NH2)2 if the yield overall reaction is 83%
Use the systematic treatment of equilibrium to determine the pH and concentrations of species in 1.00 L of solution containing 0.070 mol lysine (HL), 0.055 mol aspartic acid (H2A), and 0.0080 mol NaOH. Consider just acid-base chemistry.
Write the structures for the major monobromination products that would be formed from each of the following substrates used. Explain your predictions.
At 25 C, the standard hydrogen electrode (SHE) has a half-cell potential that is defined to be 0.00 volts. If the pH is increased at this electrode (keeping everything else the same), at what pH will the half-cell potential be equal to -0.337 volt..
explain why there is a difference in spectrophotometric response during titration before and after the equivalence point by placing the statements below into the appropriate categories.Now, calculate the concentration of apotransferrin present in ..
Arrange the elements Li, Be, Ne, and Ar in increasing order of the energy required to remove an electron from their respective gaseous atoms.
Why do humans sweat and dogs pant? Explain the purpose and the reason it is effective. Why is water consiered the universal solvent
Looking for a good explanation of how a typical 1H NMR spectrum can be obtained, outlining the physical basis for achieving the absorption of radio-frequency energy.
Suppose 93.0 g of HI(g) is placed in a glass vessel and heated to 1107K. At this temperature, equilibrium is quickly established between HI(g) and its decomposition products, H2(g) and I2(g)
