The liquid in the open-tube manometer in fig. 12.8a is mercury, y1 = 3.00 cm, and y2 = 7.00 cm. atmospheric pressure is 980 millibars. (a) what is the absolute pressure at the bottom of the u-shaped tube? (b) what is the absolute pressure in the open tube at a depth of 4.00 cm below the free surface? (c) what is the absolute pressure of the gas in the container? (d) what is the gauge pressure of the gas in pascals?

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
