Which statement about the hybridized oxygen molecule in water(sp3 hybridized oxygen) is not correct? The electrons remain in their assigned orbitals. The overall energy of the sp3 orbitals is exactly the same as the energy for the original orbitals in oxygen. Two sp3 orbitals are filled by lone electron pairs, so they cannot bond to another atom. There are two sp3 unpaired electrons prepared to bond to one hydrogen atom.
A pressure gauge on a welder's tank gives a reading of 22.4 psig.The barometer reading is 26.6 in. Hg. Calculate the absolute pressure in the tank in:
