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.
Answer:
The cube will contain 8000 mL of the fluid.
Explanation:
- Knowing that the volume of the cube = L³.
where, L is the edge length.
∴ V of the cube = L³ = (20.0 cm)³ = 8000 cm³.
Knowing that 1.0 cm³ = 1.0 mL.
<em>∴ The cube will contain 8000 mL of the fluid.</em>
Answer:
CaO + H2O= Ca(OH)2
Explanation:
The rule of balancing chemical equation states that the total number of atoms an element on the right hand side, must equal the total number of atoms of the same element on the left hand side of the reaction equation. This rule is satisfied in the equation above. For example, there are two oxygen atoms at the RHS and two at the LHS.
