Rocks are being weathered when?

Chemistry
1 answer:
poizon [28]3 years ago
5 0

Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering.

Producer gas is a fuel formed by passing air over red-hot coke (amorphous carbon). What mass of a producer gas that consists of
Karolina [17]

Producer gas is a fuel that is produced by burning biomass with an air deficit passed over red-hot coke (amorphous carbon). This gas is nothing but a mixture of gases such as hydrogen (H), carbon monoxide (CO), carbon dioxide (CO₂) and nitrogen (N₂).

The equation of producer gas is as follows -

                            CO₂ + 2N₂ (air) → CO + 2N₂

                            ΔH = -27.06 kcal

We know that,

1 Ton = 1000 kg

Mass of coke needed to form producer gas = 1.75 tons = 1750 kg

Given values,

Carbon monoxide (CO) = 25%  

Carbon dioxide (CO₂) = 5%

Nitrogen (N₂) = 70%

One mole of carbon dioxide reacts with two moles of nitrogen to form one mole of carbon monoxide and nitrogen (producer gas).

We know that, 1 ton (1000 kg) of coke produces 470 Nm³ of producer gas, i.e.

470 × 4.359 = 2048.73 kg

1000 kg of coke produces = 2048.73 kg of producer gas

∴ 1 kg of coke produces = 2048.73 ÷ 1000 kg of producer gas

∴ 1750 kg of coke produces = 2048.73 × 1750 / 1000 = 3585.28 kg of producer gas.

Percentage yield = 87%

                             = 3585.28 × 87/100

                             = 3119.19 kg of producer gas

                             = 3.44 tons

At what temperature does benzene boil when the external pressure is 410 torr ?
kondaur [170]

The temperature at which benzene boils at a given pressure of 410 torr can be deduced from the Clausius Clapeyron equation:

ln(P2/P1) = -ΔHvap/R [1/T2-1/T1] ------(1)

where

ΔHvap = heat of vaporization of benzene

P1 = atmospheric pressure

T1 = normal boiling point

R = gas constant

These values are essentially standard values which can be obtained from any thermochemical data base

For benzene: ΔHvap = 30.72 kJ/mol and T1 = 80 C = 80 +273 = 353 K

R = 0.008314 kJ/K.mol

P1 = 760 torr

P2 = 410 torr

Substituting these values in equation (1) we get:

ln(410/760) = -30.72/0.008314 [1/T2-1/353]

T2 = 337 K

or, T2 = 337 - 273 = 64 C
