Phosgene (cocl2) is a nasty gas used occasionally in warfare. it blisters your lungs! consider the following thermodynamic data: cocl2(g)⇀↽co(g) + cl2(g)at 600 k, kp is 1.2×10−3. if you put 4.79atm of cocl2(g) into a vessel of fixed volume and hold the temperature at 600 k, what is the equilibrium pressure of cl2(g)? you must use a quadratic to solve this.

When a comet collides with earth, it adds material to our planet and causes great damage. therefore, a collision like this is a a. destructive force b. constructive force c. geologic process and event d. constructive and destructive force

How much energy is made when a pice of wood burns. how do you know

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
