The airplanes parts and functions​
SpyIntel [72]

Answer: The main sections of an airplane include:

fuselage: The plane’s body, or fuselage, holds the aircraft together, with pilots sitting at the front of the fuselage, passengers and cargo in the back.

Wings: An aircraft’s wings are critical to flight through the production of lift, but they have many parts of the wing to control this lift amount and direction.

Cockpit: The cockpit is the area at the front of the fuselage from which a pilot operates the plane

Engine: The engine(s), or powerplant, of an aircraft creates thrust needed for the plane to fly.

Propeller: An aircraft’s propeller(s) are airfoils, similar to a wing, installed vertically to create thrust to drive the plane forward.

Tail assembly: An aircraft’s tail is mainly used for stability, as well as creating lift in combination with the wings. It’s comprised of several parts.

Landing gear: Landing gear is located under the belly of the plane consisting of a wheel and strut to soften impact with the ground and may be retractable into the fuselage.

•6.5 L of a gas has a pressure of 840 mmHg and temperature of 84 0C. What will be its volume at STP
EastWind [94]

Answer:

5.5 L

Explanation:

Step 1: Given data

  • Initial volume (V₁): 6.5 L
  • Initial pressure (P₁): 840 mmHg
  • Initial temperature (T₁): 84 °C
  • Final volume (V₂): ?
  • Final pressure (P₂): 760 mmHg (standard pressure)
  • Final temperature (T₂): 273.15 K (standard temperature)

Step 2: Convert T₁ to Kelvin

We will use the following expression.

K = °C + 273.15

K = 84 °C + 273.15 = 357 K

Step 3: Calculate the final volume of the gas

We will use the combined gas law.

P₁ × V₁ / T₁ = P₂ × V₂ / T₂

V₂ = P₁ × V₁ × T₂ / T₁ × P₂

V₂ = 840 mmHg × 6.5 L × 273.15 K / 357 K × 760 mmHg = 5.5 L

the solubility product Ag3PO4 is: Ksp = 2.8 x 10^-18. What is the solubility of Ag3PO4 in water, in moles per liter?
guapka [62]

Answer : The solubility of Ag_3PO_4 in water is, 1.8\times 10^{-5}mol/L

Explanation :

The solubility equilibrium reaction will be:

Ag_3PO_4\rightleftharpoons 3Ag^++PO_4^{3-}

Let the molar solubility be 's'.

The expression for solubility constant for this reaction will be,

K_{sp}=[Ag^{+}]^3[PO_4^{3-}]

K_{sp}=(3s)^3\times (s)

K_{sp}=27s^4

Given:

K_{sp} = 2.8\times 10^{-18}

Now put all the given values in the above expression, we get:

K_{sp}=27s^4

2.8\times 10^{-18}=27s^4

s=1.8\times 10^{-5}M=1.8\times 10^{-5}mol/L

Therefore, the solubility of Ag_3PO_4 in water is, 1.8\times 10^{-5}mol/L
