The compound 1-iodododecane is a nonvolatile liquid with a density of 1.20g/ml. the density of mercury is 13.6g/ml. part a what
valina [46]

As the atmospheric pressure is, P = dgh

Here d is the density of the mercury,

g is gravitation = 9.8 m/s²

h is height of the column, P = 751 torr = (751 torr × 1 atm / 760 torr) (101325 Pa) (1 N/m² / 1 Pa) = 100125 N/m²

Where, 1 N = 1 Kg / ms²

Thus, P = 100125 Kg / m³. s²

Therefore, height of the mercury column, when the atmospheric pressure is 751 torr,

h = P / gd

= (100125 kg / m³. s²) / (9.8 m/s²) (13.6 × 10³ kg / m³) = 0.751 m

As, d₁h₁ = d₂h₂

Here, d₁ is the density of the non-volatile liquid = 1.20 g/ml

d₂ is the density of the mercury = 13.6 g/ml

h₂ = 0.751 m

Thus, putting the values we get,

h₁ = d₂h₂ /d₁ = 13.6 g/ml × 0.751 m / 1.20 g/ml

= 8.5 m

explain the relationship between the kelvin temperature of a substance and the kinetic energy of its particles
blondinia [14]

Answer:

kinetic energy is directly proportional to the absolute temperature this is because when absolute temperature is increased it tends to cause more collision of the particles which hence increases kinetic energy of the particles .

since kinetic energy is the energy due to motion

A sample of lsd (d-lysergic acid diethylamide, c24h30n3o) is added to some table salt (sodium chloride) to form a mixture. given
spin [16.1K]
1) All the CO2 comes from the C24 H30 N3 O

2) To balance C from CO2 with C from C24, the ratio of cC24 H30 N3 O to CO2 is 24 / 1

3) Convert 1.20 g of CO2 to number of moles

number of moles = mass in grams / molar mass

mass = 1.20 g

molar mass = 12.01 g/mol + 32.00 g/mol = 44.01 g/mol

number of moles = 1.2 g / 44.01 g/mol = 0.0273 mol

4) proportion

1 mol C24 H30 N3 O / 24 mol CO2 = x / 0.0273 mol CO2

=> x = 0.0273 mol CO2 * 1 mol C24H30N3O / 24 mol CO2 = 0.00114 mol C24H30N3O

5) Convert 0.00114 mol C24H30N3O to grams

molar mass = 376.5 g/mol

mass = 0.00114 mol * 376.5 g/mol = 0.429 g

6) mass percent in the mixture

mass percent = (mass of lsd / mass of mixture) * 100 = (0.429g / 1.0g) * 100 = 42.9%

Answer: 42.9%
