Answer:
<h3>The answer is 43.89 mL</h3>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 57.5 g
density = 1.31 g/mL
We have
We have the final answer as
<h3>43.89 mL</h3>Hope this helps you
Answer: Option (5) is the correct answer.
Explanation:
It is known that the ground state electronic configuration of silicon is .
And, we know that when an atom tends to gain an electron then it acquires a negative charge and when an atom tends to lose an electron then it acquires a positive charge.
As has a +4 charge which means that it has lost 4 electrons. Hence, the electronic configuration of
is
.
According to the Aufbau principle, in the ground state of an atom or ion the electrons fill atomic orbitals of the lowest energy levels first, before filling the higher energy levels.
As 2p orbital is filled after the filling of 2s orbital.
Therefore, we can conclude that 2p orbital will be occupied by the electrons of highest energy for the ground-state ion.
Explanation:
Organic compounds are defined as the compounds which contain carbon as their main element. For example, is an organic compound.
Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.
As compound A melts at and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.
Whereas compound B melts at and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature
. Hence, it is more likely to be organic in nature.
Thus, we can conclude that compound B is more likely to be an organic
compound.
