25. The amount of blood in the human body is around 5.0 L, and this amount...
The average human body contains 6.50 L of blood with a Fe2+ concentration of 2.40×10−5M . If a person ingests 5.00 mL of 23.0 mM NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion?
The average human body contains 6.40 L of blood with a Fe2+ concentration of 1.80×10−5 M . If a person ingests 8.00 mL of 12.0 mM NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion?
The average human body contains 6.40 L of blood with a Fe2+ concentration of 3.10×10−5 M . If a person ingests 5.00 mL of 12.0 mM NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion?
The average human body contains 5.00 L of blood with a Fe2+ concentration of 1.60×10−5 M . If a person ingests 9.00 mL of 12.0 mM NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion?
The average human body contains 6.50 L of blood with a Fe2+ concentration of 2.90×10−5 M . If a person ingests 9.00 mL of 11.0 mM NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion? Express the percentage numerically.
The average human body contains 6.50 L of blood with a Fe2+ concentration of 2.20×10−5 M . If a person ingests 10.0 mL of 17.0 mM NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion? Express the percentage numerically.
The average human body contains 6.10 L of blood with a Fe2+ concentration of 1.10x10-5 M. If a person ingests 12.0 mL of 10.0 mMNaCN, what percentage of iron(l) in the blood would be sequestered by the cyanide ion?
The average human body contains 5.50 L of blood with a Fe2+ concentration of 2.10×10−5mol L−1. If a person ingests 5.00 mL of 22.0 mmol L−1 NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion?
The average human body contains 5.10 L of blood with a Fe2+ concentration of 2.60×10−5mol L−1. If a person ingests 12.0 mL of 18.0 mol L−1 NaCN, what percentage of iron(II) in the blood would be sequestered by the cyanide ion? Express the percentage numerically.
Buffers are common (and extremely important) in biological systems, including in human body. One of the most important biological buffers in human blood is the buffer established between carbonic acid and bicarbonate ion (H2CO3/HCO3–). At 25 oC, H2CO3 has a Ka1 of 4.45x10–7 and a Ka2 of 4.69x10–11. a. Will Ka1 or Ka2 of H2CO3 be instrumental in determining blood pH? Briefly explain your reasoning. b. Let’s pretend that there was an equal ratio of carbonic acid to bicarbonate (note...
