A: Because a hypothesis is a educated guess
Answer:
C₆H₁₂O₆ < NaCl ≈ CH₃OH < MgCl₂
Step-by-step explanation:
The formula for <em>osmotic pressure</em> (Π) is
Π = icRT
If T is constant,
Π = kic
<em>C₆H₁₂O₆:
</em>
Π = k × 1 × 1 = k
<em>MgCl₂:
</em>
Π = k × 3 × 1 = 3k
<em>CH₃OH:
</em>
Π = k × 1 × 2 = 2k
<em>NaCl:
</em>
Π = k × 2 × 1 = 2k
The order of osmotic pressures is
C₆H₁₂O₆ < NaCl ≈ CH₃OH < MgCl₂
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:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.
