1. Aluminum has a specific heat of 0.880 J/g-deg. How many joules are needed to heat 155g of Al from 20.0oC to 75.0oC2. Characterize each of the following as saturated, unsaturated, or unable to exist. Give reasons for your answers.A. C5H12 B. C3H2 C. C8H20 D. C2H2 E. CH33. The ?H of combustion of C2H6 is 1541 kJ mol. How many kJ of energy result when 575g of C2H6 are combusted?4. Why is it that a solution of NaCl in water conducts electricity, but A solution of sucrose in water does not conduct electricity?5. Why does a 1 molal solution of ZnCl2 in water have a lower freezing temperature than a 1 molal solution of NaCl in water?
Compute the mass of Trisodium phosphate required to remove all Ca^2+ ions from 2.50 Litres of the H 2 O sample?
Determine the mass of H 2 O is formed if oxygen of 10.0L react completely in the given equation?
Determine the molar concentration of CH 3 COOH present in the vinegar?
Suppose your thermometer read consistently 1.0 o C lowered throughout both parts in the colligative properties lab. What effect would that have on your experimental value for the molar mass of your unknown solute?
How much PV work is done if 88.0 grams of C 2H 4 ethylene and 120 grams of hydrochloric acid HCl are permitted to react at atmospheric pressure and the volume change = -70.3 Litres?
In an acid/base titration, knowing that it took 13.14 mili litres of 0.1016 M sodium hydroxide, NaOH to reach the first endpoint of the titration,) from this information, mols of Phosphoric acid present in the sample is 1.335 mols.
Explain would the calculated molarity of NaOH be too high or too low If the KHP weighed in your experiment today was contaminated with some unknown inert substance.
