The total pressure in a 1.00 liter container is 725 mm Hg. The container contains water vapor and nitrogen gas. If the partial p
rusak2 [61]

Answer:

Explanation:PRESSURE: atmospheres or mm Hg; 1 atm = 760 mm Hg

TEMPERATURE: Kelvin, K, which is o

C + 273

STP: Standard Temperature and Pressure: 273 K and 1 atm (or 760 mm Hg)

BOYLE'S LAW (temperature is constant): PV = constant

This is an inverse relationship: if one variable increases the other must

decrease.

CHARLES' LAW (pressure is constant): V = constant x T

This is a direct relationship: if one variable increases so does the other.

GAY-LUSSAC'S LAW (volume is constant): P = constant x T

This is a direct relationship: if one variable increases so does the other.

<h2>Every one of this with the constant</h2>

ALEKS Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills
Nikolay [14]

2NH3(g) = N2(g) + 3H2(g)

Before decomposed :

P NH3 = 2.7 atm

After decomposed :

P N2 = 0.54 atm

P H2 = P N2 / 3 = 0.54 / 3 = 0.18 atm

P NH3 = 2.7 - 2(0.18) = 2.34 atm

Pressure equilibrium constant :

Kp = (P N2)(P H2)³ / (P NH3)²

Kp = (0.54)(0.18)³ / (2.34)²

Kp = 5.75 × 10^(-4)

Calcium chloride is added to the roadways after a snowstorm. Which colligative property is being showcased here?
vlabodo [156]

Answer:

Option (D) freezing point depression

Explanation:

Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.

Calculate the number of particles in 8grams of oxygen molecule
lana [24]
Moles of oxygen = mass/molar mass of O2 = 8/31.998 = 0.25 moles.

Number of particles = moles x 6.02 x 10^23 = 0.25 x 6.02 x 10^23 = 1.505 x 10^23 particles.

Hope this helps!
