PLEASE HELP NEED IT RIGHT NOW Which of the following shows the correct sequence of energy flow, as the different types of energy are converted from one type to the other in each stage of the process?

Chemical potential energy → Thermal energy → Electrical energy → Sound energy
Chemical potential energy → Thermal energy → Electrical energy → Sound energy

Electrical energy → Thermal energy → Chemical potential energy → Sound energy
Electrical energy → Thermal energy → Chemical potential energy → Sound energy

Chemical potential energy → Electrical energy → Thermal energy → Sound energy
Chemical potential energy → Electrical energy → Thermal energy → Sound energy

Thermal energy → Chemical potential energy → Electrical energy → Sound energy

Given that the molar mass of nano3  is 85.00  g/mol, what mass of nano3  is needed to make 4.50  l of a 1.50  m nano3solution? use  .6.75 g18.9 g255 g574 g

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
