Below Mechanism shows the mechanism of formation of diazonium ion. Aniline is treated with
Nitrosonium ion which is generated
in situ by the reaction of Sodium nitrile and strong acid. The resulting <span>
benzenediazonium ion on reaction with CuBr yields
Bromobenzene and on treatment with CuCN gives
Benzonitrile. Mechanism is as folow,</span>
Answer:
162 g Fe₂O₃
Explanation:
To find the mass of Fe₂O₃, you need to (1) convert grams C to moles C (via molar mass from periodic table), then (2) convert moles C to moles Fe₂O₃ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles Fe₂O₃ to grams (via molar mass). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The final answer should have 3 sig figs to reflect the given value.
Molar Mass (C): 12.011 g/mol
2 Fe₂O₃(s) + 3 C(s) ---> 4 Fe(s) + 3 CO₂(g)
Molar Mass (Fe₂O₃): 2(55.845 g/mol) + 3(15.998 g/mol)
Molar Mass (Fe₂O₃): 159.684 g/mol
18.3 g C 1 mole 2 moles Fe₂O₃ 159.684 g
-------------- x ---------------- x ------------------------- x ----------------- = 162 g Fe₂O₃
12.011 g 3 moles C 1 mole
Answer: 7.07 grams
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require 1 mole of 
Thus 0.052 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 1 mole of 
Thus 0.052 moles of give = of
Mass of 
Thus 7.07 g of will be produced from the given masses of both reactants.
Sorry but I don’t understand the question. Sorry I’m not any help
Answer:
Water is a compound made up of two elements—hydrogen and oxygen. ... They are both colorless, odorless gases , and they both readily react with other elements—making them "reactive" elements. But in many ways they are very different from each other. Hydrogen has the lowest density of all the elements.
