Calculate the enthalpy change, Delta H, for the process in which 44.0 g of water is converted from liquid at 0.5 °C to vapor at 25.0 °C. For water, Delta Hvap = 44.0 kJ/mol at 25.0 °C and C; = 4.18 J/(g."
• °C) for H2O(1)

Express your answer to three significant figures and include the appropriate units.

How many grams of ice at -15.5 degrees C can be completely converted to liquid at 16.4 degrees C if the available heat for this process is 5.26 x 10 ^ 3 kJ?

For ice, use specific heat of 2.01 j/(g x degrees C) and delta Hfus = 6.01kJ/mol

How do you find a theoretical mass? is there a difference between theoretical mass and theoretical yield?

The overall chemical reaction for photosynthesis isshown below: 6co2 + 6h20 → c6h12o6 + 602what mass of glucose (c6h1206) can form from71.89 g co2? (molar mass of c6h1206 = 180.18g/mol; molar mass of co2 = 44.01 g/mol)71.89 g co2=g c6h1206

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
