Blood is buffered by carbonic acid and the bicarbonate ion. Normal blood plasma is 0.024 M in HCO3 and 0.0012 M in H₂CO3. (pK₂1 for H₂CO3 at body temperature is 6.1.) If the volume of blood in a normal adult is 5.2 L, what mass of HCI could be neutralized by the buffering system in blood before the pH fell below 7.0 (which would result in death)? Express your answer to two significant figures. MHCI Given the volume from Part B, what mass of NaOH could be neutralized before the pH rose above 7.7?

Please send me answer of this question immediately and i will give you like sure sir.

At a particular temperature, suppose that 24.4 g solute is added to 50.0 g water and, after mixing, 0.3 g of the solute remains undissolved. What is the solubility of this solute at this temperature in grams per 100 g of water? (Enter in standard notation with one digit after the decimal point) Type your answer......

1. Develop a detailed separation scheme for the separation and determination of the percent composition of your sample which will be a mixture of NaCl, NH.CL, and sand. You are expected to use the properties of the components listed below and some of the techniques listed in the table in the pre-lab queries (and used in Separations I). Keep in mind that any chemistry student should be able to pick up your scheme, understand it, and use it to complete the separation and calculation of % composition. Place the scheme on a separate sheet of paper. Component Solubility (@25°C) Melting Point Hardness sodium chloride, NaCl 35 g/100 mL water 801°C soft ammonium chloride, NH&Cl 37 g/100 mL water sublimes 350°C soft sand, SIQ2 insoluble 1600°C hard Example of compounds in a container.

POST-QUESTIONS 1. After a student dissolved 0.5 g of white solid in water, she tested the conductivity and determined that the solution did not conduct electricity. The student then concluded: "when the white solid dissolved it 'just disappeared' so some sort of error must have been made because all solids are ionic compounds and, therefore, are electrolytes." Comment on the student's conclusion. Is her statement a valid conclusion? If so, identify what is correct. If not, write a conclusion that would be correct.
