Answer:

1. Reflex Conditioning

Explanation:

Conditioning is an aspect of learning where a stimulus works effectively in producing a response from an organism. This response becomes regular given the type of reinforcement that is administered to the organism. The reinforcement is usually a reward that is given to the organism.

This is what is observed in the woodpecker. The stimulus or reinforcement which proves effective in producing a continuous response from the woodpecker is the abundant supply of the birds favorite bugs. This reinforcement makes it possible for the woodpecker to become conditioned towards returning to the tree.

What is the limiting reactant when 5.6 moles of aluminum react with 6.2 moles of water?

alexira [117]

The limiting reactant when 5.6 moles of aluminium react with 6.2 moles of water is

water( H2O)

<u><em>Explanation</em></u>

The balanced equation is as below

2 Al +3 H2O → Al2O3 +3 H2

The mole ratio of Al :Al2O3 is 2:1 therefore the moles of Al2O3

= 5.6 x1/2 = 2.8 moles

The mole ratio of H2O: Al2O3 is 3:1 therefore the moles of Al2O3 produced

= 6.2 x1/3= 2.067 moles

since H2O yield less amount of Al2O3 , H2O is the limiting reagent.
