Answer:
D
Explanation:
One of the properties of metals is their abilities to form a stable compounds by losing electron(s). Metals form positive ions (cations) when they lose electron(s).
<span>During cooling, the kinetic energy of the molecules falls, be</span>cause, when cooling a substace, the particles (molecules) slow down.
The kinetic energy is related to the speed, such that the lower speed the lower kinetic energy.
Particles can translate and vibrate, in the case of gases and liquids, and only vibrate (in the case of solids).
As a substance is cooled the particles get closer and the motion (translation and vibration), slows down. You can see by the equation of the kinetic energy (KE):
KE = [1/2]mass×(speed)² that as the speed is lower the KE will also be lower.
Additionally, when the cooling does not drive a change of phase (gas to liquid, liquid to solid, or solid to gas), it drives a decrease on temperature. In this case you should know that the temperature is a measure of the kinetic energy: the lower the temperature, the lower the kinetic energy.
0.33L more water is needed to dissolve it.
Cocaine is a stimulant substance obtained from the leaves of two Coca species native to South America, Erythroxylum coca and Erythroxylum novogranatense.
<h3>What is a coca?</h3>
Coca is a plant. The leaves of the coca plant are the source of cocaine, which is an illegal that is used nasally, injected, or smoked for mind-altering effects. Cocaine is also an FDA-approved Schedule II . This means cocaine can be prescribed by a healthcare provider, but the process is strictly regulated.
<h3>What happens when you smoke coca leaves?</h3>
The smoking of coca paste causes four distinct successive phases of mental disorder: euphoria, dysphoria, hallucinosis and paranoid psychosis. It can produce severe intoxication, prolonged or relapsing psychosis and, in some cases, end of life.

Answer:
amino group
Explanation:
There are twenty (20) amino acids in nature. Generally, each amino acid is structurally made up of a central carbon atom called alpha carbon attached to a hydrogen, carboxylic acid group (-COOH) and an amine group (-NH2). However, one particular amino acid called PROLINE posseses an exception to this.
Proline, which is the only cyclic amino acid, is also the only amino acid that forms a secondary amine group i.e. loss of hydrogen atoms in its amine group when in a protein structure. This means that when in a protein, PROLINE does not have an AMINE GROUP.
The lynx population increased as well because hare are the prey and the lynx are the predators.
