Answer: Yes
Explanation: It can because snow is wet and anything that is wet can
An adaption is a change or process an organism goes through to become better suited for its environment.
Example: A polar bear having white fur in order to blend in in its environment.
Acetic acid is a weak acid. So, the undissociated acid molecules exist in equilibrium with the dissociated form. The equilibrium representing the weak acidic nature of acetic acid is,
The interior of the cell membrane is hydrophobic. So, the membrane allows uncharged species (hydrophobic) to pass through it. Charged groups cannot easily pass through the membrane. We can say acetic acid can easily pass through the membrane when compared to the charged form acetate ion. At low pH, more of the molecule will cross the membrane as most of the acetic acid will be in undissociated and uncharged form at a lower pH.
of acetic acid is around 4.8. So at a pH value less than 4.8, we can say the more of the acetic acid molecules can cross the membrane.
<h2>Answer:</h2>
A.NH4Cl
<h2>Explanations:</h2><h2>How are buffer formed?</h2>
Buffers are formed by mixing an equal amount of weak base or acids and their corresponding salts.
Therefore in order to make a buffer with NH3 (a weak base), then a corresposding weak salt is required. A corresponding salt for the given base is NH4Cl

To do this consider

n
where n is an integer.
• If n > 0
move decimal point n places to the right
• If n < 0
move decimal point n places to the left
here n = 5 > 0, hence move decimal point 5 places to the right.
