. Fan blades would be an analogy for which atomic model?
2 answers:
Answer:
The correct answer is option C.
Explanation:
When fan starts the fan blades also starts spinning around axle.The axle represent the nucleus and the uniform donut like shape(with slightly fade color) formed by the movement of blades represents the electron cloud around the nucleus.
Schrodinger proposed the quantum mechanical model of the atom in which he defined the location of electrons inside an atom by electron cloud in 3-d space (as shown in the figure).

Answer: Option (c) is the correct answer.
Explanation:
A limiting reagent is defined as a reagent that completely gets consumed in a chemical reaction. A limiting reagent limits the formation of products.
For example, we have given 5 mol of A and the reaction is
Whereas when 4 mol B will react with 2 mol of A. Hence, 8 mol of B will react with 4 mol A as follows.
= 4 mol
As, the given moles of A is more than the required moles. Thus, it is considered as an excess reagent.
Hence, B is a limiting reagent because it limits the formation of products.
Thus, we can conclude that limiting reactant is the term used to describe the reactant that is used up completely and controls the amount of product that can be produced during a chemical reaction.
