Answer : The Lewis-dot structure of 
is shown below.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that carbon has '4' valence electrons, chlorine has '7' valence electron and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in = 1(4) + 2(7) + 1(6) = 24
According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
Remembering that
d = m ÷ v
d = ?
m = 104 g
v = 21 cm³
Therefore:
d = 104 ÷ 21
<span>d = 4,95 g÷cm³</span>
88 Grams because the principal of conservation of mass states total mass in equals total out so 200 in 122+88=200 out
Azeotrope is a mixture of two or more liquids whose proportions cannot be changed by simple distillation.
Explanation:
Nitic acid and water is an example of azeotrope. The composition of 68% of nitric acid and 32% of water by mass in a boiling point of 393.5k.
The composition of perchloric acid (71.6%) and water boils at 203°c. Pure iron solution weights about 10g is placed in a beaker, hydrochloric acid and nitric acid mixtures are added and heated to dissolve. Add perchloric acid until it evaporate and produces white smoke.cool it down add water and dissolve the salt.
