Answer : The length of a one-dimensional box for an electron is 
Explanation :
The energy level of quantum particle in a one-dimensional box is given as:
where,
= 479 kJ/mol = 479000 J/mol
n = energy level = 1
h = Planck's constant = 
m = mass of electron = 
L = length of a one-dimensional box = ?
Now put all the given values in the above formula, we get:
conversion used : 
Therefore, the length of a one-dimensional box for an electron is
Answer: Metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and conduct electricity easily while making metal as good conductor.
the correct answer is a. the ability of electrons to flow throughout the metal.
Explanation:
Venn diagram is a pictorial representation with of circles showing the relation between two finite sets or things. the intersection of two circles conveys the relation between those sets or things.
here in the Venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circles represents the mixture of sand and salt.
<em>so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.</em>
Answer:
Organic fertilizers are those fertilizers that are not artificially produced but are natural and has carbon in them.
Fertilizers in the broad term are used to provide nutrient to the soil and boost growth of crops.
Some of the advantages of organic fertilizers to inorganic fertilizers are:
They do not make crusts on the soil, unlike inorganic fertilizers.
They help add structure to the soil because of the good water movement into the soil
They are easier on the soil because they feed good microbes.
