Following steps are involved in this reaction,
Nitration: Nitration of benzene yield nitrobenzene.
Reduction: Reduction of Nitrobenzene yield Aniline.
Diazotization: Diazonium alt of benzene is formed from aniline.
At last diazonium salt is reacted with CuCl to yield chlorobenzene.
Answer:
D.) magnesium and sulphur
Explanation:
Generally, ionic bonds form between a metal and a nonmetal.
Generally, covalent bonds form between two nonmetals.
Generally, metallic bonds form between two metals.
Nonmetals are located on the right side of the periodic table (apart from the noble gases in the final column). Hydrogen is also a nonmetal. Metals are every other element in the periodic table.
A.) Hydrogen (nonmetal) and carbon (nonmetal) = covalent
B.) Aluminum (metal) and magnesium (metal) = metallic
C.) Silicon (nonmetal) and chlorine (nonmetal) = covalent
D.) Magnesium (metal) and sulphur (nonmetal) = ionic
Answer: 20 g
Explanation: heat received Q = m c dT
Q= 50J , dT= 25 C anc c= 0.10 J / g C
And m = Q / c dT
Answer:
78.2 g/mol
Step-by-step explanation:
We can use the <em>Ideal Gas Law</em> to solve this problem:
pV = nRT
Since n = m/M, the equation becomes
pV = (m/M)RT Multiply each side by M
pVM = mRT Divide each side by pV
M = (mRT)/(pV)
Data:
ρ = 2.50 g/L
R = 0.082 16 L·atm·K⁻¹mol⁻¹
T =98 °C
p = 740 mmHg
Calculation:
(a)<em> Convert temperature to kelvins
</em>
T = (98 + 273.15) = 371.15 K
(b) <em>Convert pressure to atmospheres
</em>
p = 740 × 1/760 =0.9737 atm
(c) <em>Calculate the molar mass
</em>
Assume V = 1 L.
Then m = 2.50 g
M = (2.50 × 0.082 06 × 371.15)/(0.9737 × 1)
= 76.14/0.9737
= 78.2 g/mol
