Best Answer: 1) As the person above said: carbon, hydrogen, and oxygen. 2) No. This is unless we consider formic acid as a fatty acid (CH2O2), but the definition of a fatty acid is a carboxylic acid with a LONG unbranched aliphatic tail that is either saturated or unsaturated.
When the tubing is cool, the warm and moist air may condense in the tubing. Not only will you not get the benefit of the moisture, but it can collect and drip into your face or gurgle with the air flow. It is often worse when the bedroom environment is cool or cold compared to the temperature of the pressurized air.
Flowback water (aka backflow water) is the murky, salty water from fracing natural gas wells. It consists of frac fluid which returns to the surface (aka the frac load recovery) as well as produced water. This water contains clay, dirt, metals, chemicals and even diesel that may have been added. The frac load recovery can be anywhere from 15-40% percent of the volume of fluid that is injected, that is forced down a well, and it flows back over a period of 3-4 weeks after fracing--most of it within 7 to 10 days. More than half of the frac fluid remains in the formation.
