We can conclude that Donald is the shortest friend.
<h3>
Who is the shortest?</h3>
This is a logical question, first, we know that the tallest friend will be on the left side, so we assume that the left position can be discarded, so we need to find who is in the right position.
Barry is not in the center and is not the youngest, so Barry is the tallest friend.
Donald is not in the center, and we know that the youngest must be on the right of Adam. So the only position left for Donald is the right one.
Then, we can conclude that Adam must be on the center and Donald on the right extreme. Then Donald is the youngest and shortest friend.

<h3>What is heat?</h3>
Heat is the transportation of energy to or from a thermodynamic system.
By the formula of heat
Where n = moles
Delta Hrxn is molar heat
q = heat
Putting the values in the equation
Thus, the heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.

Chávez's claim that the autonomic nervous system is too diffuse and slow to explain rapid and differentiated emotional responses is <u>wrong</u>.
<h3>The autonomic nervous</h3>
This system regulates certain body processes such as blood pressure and respiratory rate. It works automatically (autonomously) without the person's conscious effort.
The path of an autonomic nerve involves two nerve cells. One of them is located in the brain stem or spinal cord. It is connected by nerve fibers to another cell, located in a group of nerve cells (called autonomic ganglia). Nerve fibers from these ganglia connect with internal organs.
With these information, we can conclude that Chávez's claim that the autonomic nervous system is too diffuse and slow to explain rapid and differentiated emotional responses is <u>wrong</u>.
