Answer:
Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).
Answer:oxygen is the central atom in water,it has two lone pairs of electrons, the bond angle is 104.27° The ideal H-O-H bond angle ought to have been 109.28°
Explanation:
The presence of lone pairs causes slight distortion in the bond angles of molecules. This distortion increases with the number of lone pairs present. Water has two lone pairs hence a greater distortion compared to ammonia.
He was the first to discover the electron and isotopes.
