When there are 3 lone pairs around the central atom with 5 electron pairs, the lone pairs occupy which of the following. all axial positions one axial and two equatorial positions. two axial and one equatorial positions all equatorial positions
Tallow is stored in a vertical tank 3 m in diameter and 9?m high. The tank is insulated with a 0.05?m layer of 85% magnesia. To prevent freezing, the tallow is maintained at a temperature of 50oC by condensing steam at 135.8 kPa (abs) in a heating..
