Oxygen (O₂) is necessary for cellular respiration; it must be transported from the lungs to tissues through the bloodstream. However, O₂ is not very soluble in water. The Keq of oxygen dissolving at 310.0 K is 6.32 x 10⁻⁴. Calculate the ∆G(dissolve) for oxygen at 310.0 K, in kJ/mol.

The clouds are grey and ground is wet. a quantitative b qualitative

4. propanol and isopropanol are isomers. this means that they have a) the same molecular formula but different chemical properties. b) different molecular formulas but the same chemical properties. c) the same molecular formula and the same chemical properties. d) the same molecular formula but represent different states of the compound

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants. thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction. ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch, are burned? b) how much energy is released when 22.4g of ch. areburned?
