As you know, disinfection of water can be accomplished by bubbling cl2(g) into the water. the following questions ignore any influence of water's vapor pressure. in a. (5 points) the henry's law constant for cl2 is 8.9 x 10 m/pa (or mol l pa). if we assume that in this process the pressure of cl above the water is 101325 pa, what is the concentration of cl2 in the water? b. (10 points) cle is a water reactive gas and this reaction occurs: k-4.5 x 10-4 cl2(g) + 2h20-) hoci̇ (aq) + h,0. (aq) + cl. (aq) and of course hocl itself is an acid: ka-3.0 x 10-8 hoci (aq) + h2o (l)-oct (aq) + h,0+ (aq) what is the solubility of chlorine in water when the chlorine pressure above the water is 101325 pa? c. (5 points) what is the primary species of chlorine in the water in this situation? d. (5 points) what is the ph of the water in this situation?
yes the other ones are right just show me a pic of ur face cuz u look hot
a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -
1. measurement of atmospheric pressure
2. determining the altitude of a place
3. weather forecasting
4. calibration and checking of aneroid barometers
5. application in fluid mechanics
6. measurement of pressure in aircrafts
7. surface weather analysis
8. preparation of barographs
9. usage in physical sciences like physics, astronomy & chemistry
10. preparation of aircraft altimeters
characteristics of mercury barometer : -
1.used to define and measure atmospheric pressure.
2.on the average at sea level the column of mercury rises to a height of about 760 mm.
3.this quantity is equal to 1 atmosphere.
4.it is also known as standard atmospheric pressure.
5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
i think that is the right
