Mass of AlCl₃ : 93.39 g
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
![\large {\boxed {\bold {M ~ = ~ \dfrac {n} {V}}}](https://tex.z-dn.net/?f=%5Clarge%20%7B%5Cboxed%20%7B%5Cbold%20%7BM%20~%20%3D%20~%20%5Cdfrac%20%7Bn%7D%20%7BV%7D%7D%7D)
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M
the volume of the solution = 330 cm³=0.33 dm³
the concentration of the solution = 283 g/dm³
mass of AlCl₃ :
![\tt mass=V\times M\\\\mass=0.33\times 283=93.39~g](https://tex.z-dn.net/?f=%5Ctt%20mass%3DV%5Ctimes%20M%5C%5C%5C%5Cmass%3D0.33%5Ctimes%20283%3D93.39~g)
Answer:
Fe₂O₃
Explanation:
When Fe is burned it can form iron (II) oxide or iron (III) oxide. The reactions are:
a) Fe + 1/2 O₂ → FeO
b) 4 Fe + 3 O₂ → 2 Fe₂O₃
In the reaction "a", the mass ratio of FeO to Fe is 71.84 g FeO:55.85 g Fe =
1.29 g FeO: 1 g Fe
In the reaction "b", the mass ratio of Fe₂O₃ to Fe is 319.3 g Fe₂O₃: 223.4g Fe =
1.43 g Fe₂O₃ : 1 g Fe
According to the experimental data, the mass ratio of the product to Fe is 165.5g compound: 115.0 g Fe =
1.43 g compound: 1 g Fe
Since this ratio is equal to that of reaction "b", the empirical formula of the solid is Fe₂O₃.
Answer:
Electrophilic aromatic substitution is the reaction in which the bromobenzene is present with the presence of the nitronium ions and results in the formation of para-bromonitrobenzene.
Explanation:
Bromobenzene in the presence of nitronium ions preferntially forms para-bromonitrobenzene rather than meta or the ortho product.
so. here the reaction been mentioned refers to Electrophilic aromatic substitution.
Electrophilic aromatic substitution: An organic reaction is referred as the aromatic substitution.
In this type of organic reaction a system is present which is an organic system to which an atom gets attached which get replaced by an electrophile.
It is one of the most important reactions of the field synthetic organic chemistry.
the usage of these reactions are in synthesis of the most important intermediates which are used as the precursors in agrochemical, industrial and pharmaceutical products.
