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 MCL is another one of the four ligaments in the knee. The MCL is on the inside of the knee joint. and spans the distance from the end of the femur (thigh bone) to the top of the tibia (shin bone). The MCL resists widening of the inside of the joint, or prevents opening-up of the knee. The MCL is usually injured when the outside of the knee joint is struck, causing the outside of the knee to buckle, and the inside to widen. When the MCL is stretched too far, it may tear. A MCL injury may be an isolated injury, or it may be part of a complex injury to the knee. Other ligaments, most commonly the ACL or the meniscus may be torn along with a MCL injury. MCL injury pain is usually focused directly over the ligament.
