Answer:
17.5 g/cm³
Explanation:
We can solve this particular problem by keeping in mind the <em>definition of density</em>:
As the problem gives us both <em>the mass and the volume</em> of the box, we can now proceed to <u>calculate the density</u>:
The density of the box is 17.5 g/cm³.
Answer:
C) 2 Na + 2 H2O → 2 NaOH + H2.
Explanation:
Hello there!
In this case, according to the given chemical reactions, it is possible to firstly understand that a single displacement reaction is characterized by the presence of a single element as the first reactant and a compound as the second one, thus, yielding a compound as the first product and a single element as the second one.
In such a way, according to the given choices, it possible to note that C) 2 Na + 2 H2O → 2 NaOH + H2 is the only one with the aforementioned condition as the element at the reactants side is Na and at the products side is H2.
Best regards!
Answer:
1.Difference.
Mixtures are physically combined and can be separated by physical means while compounds are chemically combined and are separated by chemical means.
2.Mixtures do not have mixed boiling and melting points while compounds have mixed boiling and melting points.
2.Similarity.
Both mixtures and compounds are composed of two or more substances or elements combined.
Both can be separated.

Answer:
A Fridiel craft catalyst will convert benzene to acetophenone.
Permanganate catalyst can be used to convert toluene to acetophenone.
Explanation:
Benzene can be reduced to acetophenone by the addition of anhydrous aluminium chloride, AlCl₃
The mechanism is as follows:
Benzene + Acetyl choloride → acetophenone
To convert toluene to acetophenone, the following steps are necessary:
- Oxidation of Toluene to Benzoic acid.
This is done by refluxing toluene with alkaline potassium permanganate (KMnO₄+ Na₂CO₃).
-
Benzoic acid is converted to Benzoyl chloride by treating with thioyl chloride and heating at about 80 ⁰C.
-
Benzoyl chloride is treated with methyl lithium to form Acetophenone.
