Answer:
Yield of reaction is 76.7%
Explanation:
The reaction of salicylic acid with acetic anhydride to produce acetyl salicylic acid is 1:1. That means 1 mole of salicylic acid reacts with 1 mole of acetic anhydride (Acid is catalyst of reaction).
Moles of salicylic acid are:
And moles of acetic anhydride are:
As salicylic acid is limiting reactant, theoretical moles of acetyl salicylic acid are 0.04127mol. That means theoretical mass of acetyl salicylic acid is:
Thus, yield of reaction is:
<em>76.7%</em>
Answer:
tension superficial
Explanation:
Surface tension is the energy found on the surface of a liquid and is what determines the angle of wetting, in turn this angle tells us about the ability to moisten or wet a liquid before a surface.
Answer: normal fault
A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.
On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.
Answer:
A = l×b
Explanation:
Rectangle is a closed figure with 4 vertices. Each angle of a rectangle is 90 degrees. The opposite sides of a rectangle are equal.
Let l is the length of opposite sides of a rectangle and b is the breadth of the opposite sides of a rectangle.
The area of a rectangle is then given by :
A = l×b
i.e. area of a rectangle is equal to length times breadth.
