Hemoglobin (Hb) can react with both O2 and CO2 at 37 C. The reaction below demonstrates how CO can displace O2 from hemoglobin with a K=2.0 x 102.
HbO2 (aq) + CO(g) <===> HbCO (aq) + O2(g)
If the ratio [HbCO]/[HbO2] coms close to 1, death will happen. Explain what partial pressure of CO is fatal? Presume the partial pressure if O2 is 0.20atm
During lab, we tested HCl and its diluted solution which resulted as pH1.14 and diluted one was pH 2.05. Another dilution was also done using weak acid HC2H3O2 which had pH 2.86 and the diluted one being pH3.45.
Compound A, , was found to be optically active. On catalytic reduction over a palladium catalyst, 2 equivalents of hydrogen were absorbed to yield compound B. Ozonolysis of A gave two compounds. One was identified as acetaldehyde
What hybrid orbital would be expected for the central atom in each of the following: Draw the molecular structure of these compounds and label Ï? and Ï?bonds.
Calculate the pressure of the air when the whole thermometer is immersed in a bath at 100 0C. As the figure below shows, at 0 0C, the length of air space is 10 cm; and at 100 0C, it is 2 cm.
Suppose 108.3 g of hydrogen peroxide decomposes and all of the oxygen gas is collected in a balloon at 1.00 atm and 25oC. Determine the volume of the balloon.
What is the solubility of calcium phospate in pure water. Also what is the solubility of it in 0.3m Na3Po4.
Determine hydroxyl and hydrogen ion concentration in this solution. (if Ka for ammonium ion = 5.0 x 10^-10.)
At 22 °C an excess amount of a generic metal hydroxide M(OH)2, is mixed with pure water. The resulting equilibrium solution has a pH of 10.00. What is the Ksp of the salt at 22 °C
explain why the addition of s2-ion to croh3 does not result in the formation of cr2s3. the addition of s2- ion to feoh2
Element X has two natural isotopes: X-6 (6.015 amu) and X-7 (7.016 amu). Calculate the atomic mass of the element X given the abundance of X-7 is 92.5%
hydrogen and 6.8 * 10^-4 mol of oxygen. How much water can be produced if the gases react?
How many moles of H3O+ must be added to one liter of a solution to adjust the pH from 8.54 to 5.58? Use E notation and 3 significant figures.
