N2 + 3H2 ----------------- 2 NH3 so 3 moles of H2 are required to produce 2 moles of ammonia. so the molar ratio is 3:2. 10.48 grams of NH3 = 0.6165 moles so. 3H2/2NH3 = x/0.6165 X = 0.9248 moles. 0.9248 moles X 2 grams/mole = 1.8 gramsof H2. proof. 3 moles = 6 grams of H2 produce 2 moles = 34 grams NH3.
Medial Knee Ligament Injury. A medial ligament sprain or MCL injury is a tear of the ligament on the inside of the knee, usually a result of twisting or direct impact.Medial ligament injuries are common in contact sports such as football and rugby, as well as martial arts.natomy. The medial collateral ligament or MCL for short connects the thigh bone (or femur) to the shin bone (or tibia) on the inside of the knee and prevents the knee joint from moving sideways, particularly from forces on the outside of the knee.
The posterior cruciate ligament (PCL) is a ligament within the knee. Ligaments are tough bands of tissue that connect bones. The PCL -- similar to the anterior cruciate ligament (ACL) -- connects the thigh bone (femur) to your shin bone (tibia). Although it is larger and stronger than the ACL, the PCL can be torn.PCL tears make up less than 20% of injuries to knee ligaments.Injuries that tear the PCL often damage some of the other ligaments or cartilage in the knee, as well. In some cases, the ligament can also break loose a piece of underlying bone.n injury to the PCL can cause mild to severe damage. Doctors classify PCL injuries in these groups: 1  Grade I: The PCL has a partial tear. 2  Grade II: The ligament is partially torn and is looser than in Grade I. 3  Grade III: The ligament is completely torn and the knee becomes unstable.
