In order to study hydrogen halide decomposition, a researcher fills an evacuated 1.11 L flask with 0.822 mol of HI gas and allow

Elza [17]

Answer:

Kc = 168.0749

Explanation:

2HI(g) ↔ H2(g) + I2(g)

initial mol: 0.822 0 0

equil. mol: 2(0.822 - x) x x

∴ [ HI ]eq = 0.055 mol/L = 2(0.822 - x) / (1.11 L )

⇒ 1.644 - 2x = 0.055 * 1.11

⇒ 1.644 = 2x + 0.06105

⇒ 2x = 1.583

⇒ x = 0.7915 mol equilibrium

⇒ [ H2 ] eq = 0.7915mol / 1.11L = 0.7130 M = [ I2 ] eq

⇒ Kc = ([ H2 ] * [ I2 ]) / [ HI ]²

⇒ Kc = ( 0.7130² ) / ( 0.055² )

⇒ Kc = 168.0749

How do scientists determine locations for drilling for natural gas? Where are many natural gas drill sites located? (Site 2)

Alchen [17]

Explanation:

By drilling several cores miles apart , geologist can correlate the rock units and create an image what exists and where below the surface.

Combining this information with rocks exposed to the surface , which can gives clues about rock orientation below, can be a powerful tool to locating oil and gas .
