<span>Answer: Volume = pi x r² x L = 3.14 x (1.25 cm)² x 550 cm x (1 mL / 1 cm³) x (1 L / 1000 mL) = 2.70 L PV = nRT n = mass / mw PV = (mass / mw) RT mass = mw x PV / RT mass = (20.2 g/mole) x (1.78 torr x (1 atm / 760 torr)) x (2.70 L) / [(0.0821 Latm/moleK) x (308K)] mass = 0.00505 grams Ne ******** Trevor H.... check this... n = 2.7*0.237 / 8.314*308</span>

Discribe how an internal combustion engine works. What is drawback to the type of power?
Komok [63]

Answer:

An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. The force of combustion is converted into mechanical energy through the use of levers and gears. The by products of combustion include energy, water vapor, carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), and carbon monoxide (CO). The two primary drawbacks to the internal combustion engine are the primary energy source is non-renewable (fossil fuels) and the by products can have damaging effects on the environment.

An ethylene gas torch requires 3200L of gas at 3.0 atm. What will be the pressure of the gas if the Ethylene is supplied by a 25
drek231 [11]

Answer:

38.4 atm.

Explanation:

  • We can use the general law of ideal gas:<em> PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and T are constant, and have different values of P and V:

<em>(P₁V₁) = (P₂V₂).</em>

P₁ = 3.0 atm, V₁ = 3200 L,

P₂ = ??? atm, ​V₂ = 250.0 L.

∴ P₂ = (P₁V₁)/(V₂) = (3.0 atm)(3200 L)/(250.0 L) = 38.4 atm.
