Answer:
290 N
Explanation:
Total downward force = Force applied on the door in bringing it down + weight of the door
Total downward force = 80 + 210
Total downward force = 290N
The result of acid on rain on buildings and bridges would be decay and rotting, the chipping and loss of cement.
Answer:
Phospholipids are carried in the blood and deposited in vital tissues such as the brain and the liver where they serve as protection to these vital organs.
Explanation:
Lipids is another name for fats. These fats play many crucial roles in the body. Phospholipids are water soluble fats. They are important in building the protective barrier, or membrane, around body cells. In blood and other body fluids, these phspholipids usually form structures that enclose fat and carry it throughout the bloodstream to the organs where they are stored in the body.
These phospholipids also play an important role of serving as a protection to vital organs in the body such as the liver and brain. Hence, a large amount of phospholipids are found in the liver and brain where they serve as protection to these vital organs.
Humans disturb the earth and because of this, the earth is weakened
The equation is 2 NH3 (g) ⇀↽ N2 (g) + 3 H2 (g)
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.
