Question- At 1 atm, how much energy is required to heat 83.0 g of H2O(s) at 2.0°C to H2O(g) at 131.0°C?
Please illustrate work if possible thanks
Question- If the initial concentrations of HPO4 and H2C03 are both equal to 0.100 M, and the initial concentrations of H2P04 and HC03 are both equal to 0.000 M, in which direction will the reaction shift in order to reach equilibrium
Question- Arrange the following aqueous solutions in order of increasing vapor pressure at 25C: 0.35 m c3H4(OH)2; 0.50 m sugar; 0.20 m KBr; and 0.20 m Na2SO4.
