Changes in the composition of the atmosphere have caused gradual changes in earth's _______ throughout history, causing changes
bearhunter [10]

climate

Changes in the composition of the atmosphere have caused gradual changes in earth's <u>climate</u> throughout history, causing changes in plant and animal life that contributed to mass extinctions.

The following are some of the reasons:

  • UV light
  • climate
  • pollutants
  • hydrofluorocarbons

heat

  • The surface of the Earth warms up as sunlight strikes it.
  • Surface-emitted infrared light is absorbed in the atmosphere and transformed into heat.
  • The temperature close to the surface rises as a result of this heat being trapped in the atmosphere.
<h3>UV light:</h3>
  • indirect impacts of climate change on UV radiation from the surface.
  • By changing the concentrations of ozone, UV-absorbing tropospheric gases, aerosols, and clouds in the atmosphere, climate change may have indirectly affected UV radiation levels in the past.
  • These influences are probably going to persist in the future.
<h3>climate:</h3>
  • People are at risk from food and water shortages, greater flooding, high heat, an increase in disease, and economic loss due to climate change.
  • Conflict and human migration are potential outcomes.
  • Climate change is the top hazard to world health in the twenty-first century, according to the World Health Organization (WHO).
<h3>pollutants:</h3>
  • these are also resulting in the increase of temperature of the Earth and is also damaging ozone layer.

The isomerization reaction, ch3nc → ch3cn, is first order and the rate constant is equal to 0.46 s-1 at 600 k. what is the conce
Harlamova29_29 [7]
According to this formula :
㏑[A] /[Ao] = - Kt 
when we have Ao = 0.3 m 
and K =0.46 s^-1
t = 20min = 0.2 x 60 =12 s
So by substitution :
㏑[A] / 0.3 = - 0.46 * 12
㏑[A] / 0.3 = - 5.52
by taking e^x for both side of the equation we can get [A]
∴[A] = 0.0012 mol dm^-3
