Hemoglobin (Hb) can react with both O2 and CO at 37 C. The reaction below shows 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] comes close to 1, death will happen. What partial pressure of CO is fatal? Assume the partial pressure of O2 is 0.20 atm (since air is 20% O2).
Suppose that 150.2 J of heat energy is required to completely vaporize 5 g of a pure liquid. If the molar mass of the liquid is 95.64 g/mol, what is the molar enthalpy of vaporization of the liquid
Calculate w (in kJ) when 390 g iron (III) oxide (MM = 159.7 g/mol) reacts with excess carbon to produce carbon dioxide gas at 426 K.
