The Lewis structure of which molecule requires resonance structures?A.) MgCl2B.) SiO2C.) SO2D.) OCl2
1 answer:
Answer: C.) SO2
Explanation: Sulfur Dioxide is the gaseous molecule which can show the resonance through lewis dot structure due to the presence of lone pairs of electrons present on all of the three atoms of the molecules. Moreover , Sulphur forms pie bond with the oxygen using p orbitals which forms a network of the conjugated system that help to elaborate the reason of the formation of the resonance structure.
Options (a), (b), and (d) cannot form resonating structures as they involve the formation of the chemical bonds through single sigma bond.

Answer:
The correct option is C
Explanation:
From the question we are told that
The reaction is
Generally
Here is the change in enthalpy
is the change in the internal energy
is the difference between that number of moles of product and the number of moles of reactant
Looking at the reaction we can discover that the elements that was consumed and the element that was formed is and
and this are both gases so the change would occur in the number of moles
So
The negative sign in the equation tell us that the enthalpy would be less than the Internal energy
If the forces are equal and in opposite directions, the net force will equal zero.
Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.
<em>F = ma </em>
The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
