Answer:
the degree to which they decrease CNS activity
Explanation:
Drugs can be classified as;
✓hallucinogens, example is (LSD)
✓ stimulants, example is (cocaine)
✓opium-related painkillers example is (heroin)
✓depressants
Depressants can be regarded as medicines, that lowers neurotransmission levels, that is depressing or reducing arousal or stimulation as regards to various areas of the brain. these could be tranquilizers, as well as hypnotics and
sedatives. They are drugs used in slowing brain activity, therefore, making them useful when treating anxiety, sleep disorders, panic and acute stress reactions.
Example of Depressants are;
✓Xanax
✓Halcion
✓Klonopin
✓Librium
It should be noted that Depressants are often classified according to the degree to which they decrease central nervous system (CNS) activity.
Answer:
C. Chemical Energy
Explanation:
The energy that stored in the substance or in compounds is called chemical energy which released when the substance reacts.
A substance is made up of atoms and molecules and chemical energy is present in those atoms or molecules. When a chemical reaction takes place, these energy released from atoms and molecules.
Chemical energy can be released in the form of thermal energy (heat) and mechanical energy (working ability).
Hence, the correct answer is "C. Chemical Energy".
Answer:
The drinks that the student should avoid - if he wants to avoid damage to his teeth - are drinks C and E, since they are acidic, according to their pH.
Explanation:
pH measures the acidity or alkalinity of a solution, taking into account the amount of hydrogen ions present in it, and established on a scale that goes from 0 to 14.
In chemistry, pH is derived from the formula that indicates:
<em>pH = - Log₁₀ αH⁺</em>
, where α is the activity of hydrogen ions.
A solution with a pH of 7 is considered neutral, above this value it is an acidic solution and below this value it is called acidic.
According to this:
- <em>Acidic drinks are: drink C (5.3) and E (2.4).</em>
- <em>The basic drinks are: drink A (11.9) and drink D (9.8).</em>
- <em>The neutral drink is the drink B (7), which corresponds to water.</em>
Sensory is the answer to your question .
Answer:
The cation affects the intensity of the color more than the color of the solution.
Explanation:
According to Beer Lambert law, the intensity of the colour of the solution depends on the concentration of the specie responsible for the colour in the solution.
Let us recall that transition metal compounds are coloured in solution due to electronic transitions.
Therefore, the cation affects the intensity of the color more than the color of the solution.
