2. Iron has a density of 7.86 g/cm). A sample of an unknown metal is measured and found to be
alekssr [168]
The volume of sample = 2.25(1.5)(2.25) = 7.59375 cm3
Density = mass / volume
Density = 55.75 / 7.59375 = 7.34156 g/cm3

As the density of iron is 7.86 g/cm3 instead, it is not iron

Reaction of HBr with 3-methylcyclohexene yields a mixture of four products cis-and trans-1-bromo-3-methylcyclohexane and cis-and
Umnica [9.8K]

Answer:

See explanation

Explanation:

The mechanism of this reaction including intermediates are shown in the image attached to this answer.

The reaction of  HBr with 3-bromocyclohexene yields trans-1,2-dibromocyclohexane as the sole product because; the proton first attacks the  3-bromocyclohexene  and a brominium ion is formed. This brominium ion is a cyclic intermediate as shown in the image attached.

Attack of a bromine ion afterwards must lead to the formation of trans-1,2-dibromocyclohexane as shown.

When 429 mmhg of argon, 1.2 atm of neon, and 225 mmhg of helium are mixed, what is the total pressure?
Dmitry_Shevchenko [17]

The total pressure  1566 mm Hg.

Pressure is the force applied perpendicular to the floor of an object per unit location over which that pressure is shipped. Gauge strain additionally spelled gage pressure is the pressure relative to the ambient stress. pressure.

The SI unit of stress is pascal which is identical to one newton in keeping with rectangular meter. apparently, this name was given in 1971. earlier than that pressure in SI became measured in newtons in line with square meter.

Partial pressure of Argon = 429 mm Hg

Partial pressure of Neon = 1.2 atm

   ∵ 1 atm = 760 mm Hg

=> 1.2 atm = 1.2 * 760 mm Hg

                 = 912 mm Hg

Partial presser of He = 225 mm Hg

S0, Total pressure = Par + P ne + P he

                              =  ( 429 + 912 + 225 ) mm Hg

                              = 1566 mm Hg
