water acts as the solvent for this experiment
we use to calculate R f values and compare with know to determine the compound is made of example in forensic science to find DNA, amino acids
most soluble one will travel the most
c to b to a (A most further travelled)
Explanation:
This quest in requires general knowledge on chromatography
Answer: The average rate of the reaction during this time interval is, 0.005 M/s
Explanation:
The given chemical reaction is:
The expression will be:
where,
= final concentration of 
= 0.025 M
= initial concentration of = 0.100 M
= final time = 15 minutes
= initial time = 0 minutes
Putting values in above equation, we get:
Hence, the average rate of the reaction during this time interval is, 0.005 M/s
Answer:
Explanation:
The compound 
is .
The reaction included are:
(because bromine is less reactive than chlorine)
But , because of hexane the solution get dilute and its color changes to orange.
Now, NaI is added and we know Br is more reactive than I.
Therefore it replace it.
Reaction: 
Purple color develop due to formation of Iodine.
A curved line or surface cannot be measured by a straight scale, a measuring tape or thread must be used instead.To measure a curved line using a thread, follow the below steps:
Tie a knot at one end of the thread.
Place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight.
Place your thumb at the other end of the measured portion and measure next straighter portion.
Repeat the above step till the end of line is reached. Make a knot at the end of the line.
Now, straighten the thread and measure the length of the two knots on a scale.

Answer:</h3>
B. 2010.62 ft³
<h3>
Explanation:</h3>
<u>We are given</u>;
Dimensions of the cylinder as 10 ft × 16 ft
We are going to take;
- Height as 10 ft
- Diameter as 16 ft
We are required to calculate the volume of the cylinder
- Volume refers to the amount of space occupied by an object.
- It is calculated depending on the shape of the solid.
In this case;
Volume of a cylinder = πr²h, where r is the radius and h is the height.
Radius, r = 8 ft
Height, h = 10 ft
Therefore;
Taking π as 3.142
Volume of the cylinder = 3.142 × (8ft)² × 10 ft
= 2010.62 ft³
Thus, the volume of the cylinder is 2010.62 ft³
