Answer:One mile is also equal to 5,280 feet or 1,760 yards. The mile is a US customary and imperial unit of length. Miles can be abbreviated as mi, and are also sometimes abbreviated as m. For example, 1 mile can be written as 1 mi or 1 m. Inches. An inch is a unit of linear length measure equal to 1 / 12 of a foot or 1 / 36 of a yard.

Answer:
25 mL
Explanation:
Step 1: Given data
- Concentration of the concentrated solution (C₁): 2 M
- Volume of the concentrated solution (V₁): ?
- Concentration of the diluted solution (C₂): 0.1 M
- Volume of the diluted solution (V₂): 0.500 L
Step 2: Calculate the volume of the concentrated NaCl solution
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 0.1 M × 0.500 L / 2 M
V₁ = 0.025 L = 25 mL
Answer:
a. All of the below
Explanation:
Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture.
TLC can be used to analyze a chemical reaction to determine if the reactants have been consumed and a new product has formed. Running a tlc of ferrocene, the acetylferrocene product mixture, and co-spot, when you view the TLC plate under a UV light, you will notice that acetylferrocene product is on the right-most lane, this shows that the reaction appears to be a success: the higher spot of ferrocene has been consumed), and a new product spot is present. From these we can observe that the we can use this to identify the number of products of the reaction, determine if the starting material is still present in the reaction and the elution in a chromatography column of the starting material and products. Therefore, all the choices are correct.
