Concentrated hydrochloric acid is 38% HCl by weight and has a density of 1.19 g/mL. A solution is prepared by measuring 25 mL of the concentrated HCl, adding it to water, and diluting to 0.800 L. Calculate the approximate molarity of this solution from the volume, percent composition, and density.
Calculate the pH of each of the following solutions. (a) 0.500 M HONH2 (Kb = 1.1 10-8) (b) 0.500 M HONH3Cl
If 50.00mL of propylene glycol has am ass of 51.80g, what is its density in SI units (kg/m^3).
A balloon filled with helium has a volume of 2.41 L on a warm day at 311 K. It is brought into an air-conditioned room where the temperature is 295 K. What is its new volume.
6NO2+2H2O=4(HNO3)+2NO. For this equation, how many grams of nitrogen dioxide are needed to react with 3.70mol of H2O? How many grams of nitrogen monoxide are produced when 2.18mol of H2O react?
The buret is misaligned with the drop counter so approximately 10 drops of NaOH are added to the HCl before they are counted
What is the pH of a buffer prepared by adding 0.809 mol of the weak acid HA to 0.406 mol of NaA in 2.00L of solution? The dissociation constant of is 5.66*10-7
Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years
what is the correct electron configuration for Cr (chromium). Chose the proper Lewis dot structure for the compound or poliatomic ion: Sulfur Dioxide (SO2).
The reaction vessel feels cooler. b.The value of K becomes smaller. c.The equilibrium will shift to the left. d.The reaction vessel feels warmer.
Calculate the pH of each of the following strong acid solutions: 5.00 mL of 1.00 M HCl diluted to 0.500 L d) a mixture formed by adding 50.0 mL of 0.020 M HCL to 150 mL of 0.010 M HI
the osmotic pressure of the solution is 0.443 atm. What is the percent ionization of this acid? I got 20% but its wrong
