The lack of a spinal column is the distinguishing characteristic of invertebrates.
<h3>What is an Invertebrate?</h3>
These are organisms which lack a backbone(vertebral column) while vertebrates on the other hand have it.
This is why option C was chosen as the most appropriate choice in this scenario.

To be floating, the gravity force of the iceberg should be same as the buoyancy force that result from the difference of the ice and water density.
The density of ice is 920 and water is 1030, then the difference should be: 1030kg/m3-920kg/m3= 110kg/m3
Let say that the volume of ice below the water is volume1 and the volume above the water(exposed volume) is volume2.
You can get this equation
volume1+volume2= 100%
volume1= 100%- volume2
Insert it into the buoyancy and gravity force will result
buoyancy=gravity
110kg/m3*volume1= 920kg/m3 *volume2
110kg/m3*(100%- volume2)= 920kg/m3 *volume2
110kg/m3 - 110kg/m3*volume2= 920kg/m3 *volume2
110kg/m3 = 1030kg/m3 *volume2
volume2= 110/1030= 0.1067= 10.7%
Answer:
The high concentration of the iron ion ensures that the reaction is favored to go to the right
Explanation:
According to Le Chateliers principle, when a constraint such as a change in concentration, pressure or volume is imposed on a chemical system in equilibrium, the system will readjust itself in order to annul the constraint. This is done by shifting the position of equilibrium, either to the left hand side or the right hand side depending on the requirement of the system based on the imposed constraint. Equilibrium his now reestablished in the system as a result of this readjustment.
Since there is a high(excess) concentration of iron in the system, it can be safely assumed that the equilibrium concentration of the FeNCS2+ is equal to the initial concentration of SCN- ion present. This implies that the equilibrium position moves towards the right hand side according to Le Chateliers principle.
