Wet air containing 4.0mol% water vapor is passed through a column of calcium chloride pellets. the pellets absorb 97.0% of the water and none of the other constituents of the air. the column packing was initially dry and had a mass of 3.40 kg. following 5.0 hours of operation, the pellets are weighed and found to have a mass of 3.54 kg. a) calculate the molar flow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas. b) the mole fraction of water in the product gas is monitored and found to have the value calculated in part (a) for the first 10 hours of operation, but then it begins to increase. what is the most likely cause of the increase

distance, luminosity, brightness, radius, chemical composition, and temperature

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
