The following tube has dimensions d1=1.16 cm and d2=3.60 mm. Air (density = 1.28 kg/m3) flows through the tube at a rate of 1100.0 cm3/s. Assume that air is an ideal fluid. What is the height h of mercury (density = 13600.0 kg/m3) in the right side of the U tube?

When water mixes with carbon dioxide in the air, what is formed? H2O + CO2 --> H2CO3 carbonic acid I dont think this is correct because there is no aid in co2. It just ends up to be CO2 in liquid form. Basically water with air is carbonated water. that is definitely correct...
