A closed system initially containing 1×10^-3 hydrogen 2×10^-3M iodine at 448 degree Celsius and is allowed to reach equilibrium.
GaryK [48]

Answer:

Kc = 50.5

Explanation:

We determine the reaction:

H₂  +  I₂   ⇄   2HI

Initially we have 0.001 molesof H₂

and 0.002 moles of I₂

If we have produced 0.00187 moles of HI in the equilibrium we have to know, how many moles of I₂ and H₂, have reacted.

           H₂     +      I₂      ⇄   2HI

In:     0.001       0.002           -

R:       x                 x                2x

Eq:  0.001-x    0.002-x      0.00187  

x = 0.00187/2 = 9.35×10⁻⁴ moles that have reacted

So in the equilibrium we have:

0.001 - 9.35×10⁻⁴ = 6.5×10⁻⁵  moles of H₂

0.002 - 9.35×10⁻⁴ = 1.065×10⁻³ moles of I₂

Expression for Kc is =  (HI)² / (H₂) . (I₂)

0.00187 ² /  6.5×10⁻⁵ . 1.065×10⁻³ = 50.5

Noise Pollution: An Invisible Threat to Humans and animals.
soldi70 [24.7K]

Answer:

Explanation:

Noise pollution occurs when we have a house which is more than 65 decibels. The effects of noise pollution include physical effects which can be respiratory agitation, headaches, high blood pressure, etc.

Another effect is the psychological effect such as depression, anxiety, fatigue etc. Stress can also lead to sleep disorders and lack of concentration.

The ways to reduce noise pollution are:

1. Using awareness campaign: People should be told about the harmful effects of noise. This will be vital in reducing noise.

2. Government control: Government can play their role by telling those who doesn't adhere to laid out rules regarding noise to pay a fine. Anyone found wanting should pay a fine.
