Ammonia is manufactured by combining nitrogen and hydrogen directly. Nitrogen and hydrogen are compressed to about 250 atmospheres and heated to about 4000 centigrade. They are then passed over an iron catalyst to form ammonia. The reaction is reversible, and unchanged nitrogen and hydrogen are recycled.
Adorable animal families that will make you aww. Lateral flexion is the anatomical term for the movement of bending sideways at the waist. Alternately known as side bending or lateral trunk flexion, it can refer to movement of the entire spine in a lateral direction, of the neck only, or of a segment of the spine.his is because lateral flexion affects entire portions of the spine, not just two adjacent vertebrae. Side bending from the waist involves movement in both the thoracic and lumbar spine; laterally flexing the head requires the involvement of most of the cervical spine.
Side bending is called lateral flexion. The orientation of the facet joints in the lower back permits fairly free side bending. The normal range of motion in the lumbar spine is about 20 degrees to each side. Lateral flexion is primarily limited by tension in the ligaments and muscles on the opposite side of the spine.he range of motion, or how far your spine can move, is limited by the disks between the vertebrae, the ligaments that tie the vertebrae together and the orientation of the facet joints on the back part of the vertebrae.
