<span>Chlorobenzene is an aromatic organic compound with the chemical formula C6H5CI. This of benzene in the presence of a catalytic amount Lewis acid such as ferric chloride, sulfur dichloride, and anhydrous aluminum chloride. Upon entering the body, typically via contaminated air, chlorobenzene is excreted both via the lungs and the urinary system.</span>
Answer) D. ketone. Im not sure if its right tho
TITRATION is the process of reaching equilibrium between acids and bases.
a pure compound because an element is untouched and is just itself
Answer:
Explanation:
Molar mass of Argon
= 35.96755 x .00337 + 37.96272 x .00063 + 39.96240 x .99600
= .12121 + .0239165 + 39.80255
= 39.95
Molar mass of silicon
27.97693 x .9223 + 28.97649 x .0467 + 29.97376 x .0310
= 25.803 + 1.35320 + .929
= 28.08
b )
No of atoms of Si in 78.2 g = 78.2 x 6.02 x 10²³ / 28.08
= 16.76 x 10²³ .
c )
42 Ar / 40 Ar = 1.05006
42 Ar / 39.95 = 1.05006
42Ar = 41.95
2 )
C₁₆H₁₅F₂N₃O₄S
Mol weight = 16 x 12 + 1 x 15 + 2 x 19 + 3 x 14 + 4 x 16 + 32
= 192 + 15 + 38 + 42 + 64+ 32
= 383
No of molecules = .078 x 6.02 x 10²³ / 383
= 1.226 x 10²⁰ molecules .
