What is a triangle?</h3>
A triangle is a three sided figure. The figures are not shown here. However, two triangle may be regarded as similar or congruent by the following conditions;
1) Side angle side (SAS)
2) Side side side (SSS)
3) Angle Angle side (AAS)
Since the triagles are not shown here, the similarity of the triangles can not be established.

Answer:
grams
Explanation:
Complete question is
You are asked to pre pare a pH = 4.00 buffer starting from 1.50 L of 0.0200 M solution of benzoic acid
(C6H5COOH)
and any amount you need of sodium benzoate
(C6H5COONa)
How many grams of sodium benzoate should be added to prepare the buffer? Neglect the small volume change that occurs when the sodium benzoate is added.
Solution
Given
pH of the buffer solution 
Concentration of C6H5COOH
M
Volume of the buffer solution
L
value for benzoic acid is 
Concentration of sodium benzoate

Substituting the given values we get

Number of moles in sodium benzoate

Mass of sodium benzoate

No because anything can freeze but the warmer it is the longer it will take to be fully frozen. If you want the substance to freeze faster have it be cold by putting it in the fridge or something.
The answer will be b. membrane.
