Answer:
7p
Explanation:
principal quantum number is 7
n=7( principle shell)
angular momentum quantum number gives sub shell
l = 1 means it is p orbital
so answer is 7p orbital
Answer:
Gravity
Explanation:
All matter exerts a force, which is called , that pulls all other matter towards its center. The strength of the force depends on the mass of the object: the Sun has more gravity than Earth, which in turn has more gravity than an apple. Also, the force weakens with distance. Objects far from the Sun won’t be influenced by its gravity.
Answer:
Blue color of iodine-starch complex is disappear upon hysrolysis
Explanation:
Starch:
Starch is a polysaccharide
it is energy reservoir.
starch is made of monomers of glucose in a chain form.
The simplest form of starch is linear polymer amylose.
Iodine Test:
In this test iodine solution added to the solution to check the presence of starch.
Iodine solution = elemental iodine + KI
Result of Iodine Test:
when the iodine solution (I₃⁻) is added to a solution it show two types of result.
if the starch is present this I₃⁻ form a complex with amylose chain of starch and impart a dark blue color.
if starch is not present then the color will be orange or yellow.
Hydrolysis of Starch:
Hydrolysis of starch is carried out by an enzyme, this enzyme break down the starch into simpler sugar molecule.
So,
When the hydrolysis of starch occur the starch convert to glucose. Then the blue color of starch and iodine complex formed during iodine test is disappear that will be the indication of hydrolysis of starch.
