Use this equation, your algebra skills and your logic to see how tall a water barometer would be!

Calculate the height of a column of water equivalent to 1.00 bar. The density of water is 1.00 g/cm3; the density of mercury is 13.53 g/cm3. Physical Chemistry 1  please provide complete solution.

In the vacuum of space, the air pressure is so low, that water boils and freezes at the same time. At what pressure is the boiling point of water the same as its freezing point? Use the same experimental P1 and T1 values as in the previous calculations, but this time use T2 as the freezing point of water. Make sure your units cancel. P1= 1500 torr T1= 400 P2 (Freezing Point)= 351.4

1) Determine the mass of the condensed portion of the unknown that you placed in the test tube. 2) Use the mass of the water in the test tube and it’s density to calculate the volume of the test tube. 3) Use the calculations from Questions 1 & 2, along with the temperature of the boiling water bath and the barometric pressure of the room, to calculate the molar mass of the unknown compound. 4) identify the unknown liquid substance that you tested. 5) Using the SAMPLE data, calculate the molecular weight of the unknown and determine the identity from the chart.

Based on the charles' law, the following errors in procedure will affect the experimental result. Explain how wach action causes an incorrect result. Procedure(part A) 1) Student A was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing. 2) Student B used the measurement of Flask no. 1 to be 250mL, without measuring the volume directed. 3) Student C recorded the temperature in degrees Celcius and used these values in calculations. Procedure(part B) 4) Water remained on the outside of the flask and on the foil when the final mass was determined.

Question 9 of 10 Komal found that her vial of isopropyl alcohol showed a much better surface tension bubble shape (a higher bubble) than her vial of water. Her peer group suggested some experimental errors that may have caused this to happen. Which three experimental errors are most likely to have occurred? OA. Someone might have jiggled the table and made the water surface tension bubble spill over. B. Komal could have mixed up the labels on the vials. C. The water could actually have been saltwater instead of pure water. D. Someone might have jiggled the table and made the isopropyl alcohol surface tension bubble spill over.
