Vikentia [17]

C.)Cool air near the surface forms high-pressure areas; warm air forms low-pressure areas.

Explanation:

The relationship between air temperature and high and low pressure air is such that cool air near the surface forms high-pressure areas and warm air forms low pressure areas.

  • Cool air is closer to the surface because it has low kinetic energy to move. It is denser.
  • Warm air rises sharply away from the ground surface.
  • They form low pressure areas and their molecules are wide apart due to their high kinetic energy. The air is less dense.

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
ella [17]

Answer:

NaOH(aq)

Explanation:

NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)

Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

If 1.2 moles of ideal gas occupy a volume of 18.2 L at a pressure of 1.8 ATM what is the temperature of gas in degrees Celsius.
Novosadov [1.4K]

Answer: A 59.5 degree celcius

The equation that we will use to solve this problem is :

PV = nRT where:

P is the pressure of gas = 1.8 atm

V is the volume of gas = 18.2 liters

n is the number of moles of gas = 1.2 moles

R is the gas constant =  0.0821

T is the temperature required (calculated in kelvin)

Using these values to substitute in the equation, we find that:

(1.8)(18.2) = (1.2)(0.0821)(T)

T = 332.5 degree kelvin

The last step is to convert the degree kelvin into degree celcius:

T = 332.5 - 273 = 59.5 degree celcius
