Answer : The resonance structure of is shown below.
Explanation :
Resonance structure : It is defined as when more than one Lewis structure can be drawn, the molecule or ion is said to have resonance.
Resonance is the concept where electrons (bonds) are delocalized over three or more atoms which cannot be depicted with one simple Lewis structure.
First we have to draw Lewis-dot structure.
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 sulfur has '6' valence electrons, carbon has '6' valence electrons and nitrogen has '5' valence electron.
Therefore, the total number of valence electrons in = 6 + 4 + 5 = 15
According to Lewis-dot structure, there are 7 number of bonding electrons and 8 number of non-bonding electrons.
In SCN, carbon atom is the central atom and sulfur and nitrogen are the neighboring atoms.
The resonance structure of is shown below.
Answer:
Is water the only liquid? If not, name 5 more
Water, ethanol, household bleach, blood, paint, milk, gasoline, mineral oil, acetone and butyl alcohol are examples of liquids. Liquids' properties allow them to flow or be poured easily into containers, lava
water is not the only liquid.
<u>Answer:</u> The molar mass of molecule X is 162.5 g/mol
<u>Explanation:</u>
We are given:
0.9 % of NaCl
This means that 0.9 grams of NaCl is present in 100 grams of solution
5 % of molecule X
This means that 5 grams of molecule X is present in 100 grams of solution
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
Or,
where,
i = Van't hoff factor
R = Gas constant =
T = temperature of the solution
According to the question:
Osmotic pressure of both the solutions are same.
So, the equation becomes:
where,
Putting values in above equation, we get:
Hence, the molar mass of molecule X is 162.5 g/mol
