Each of the prefixes means a different thind:
Nano means 0.000000001
Kilo means 1000
Milli means 0.001
Centi means 0.01
Out of these four, the biggest is b: 1 kilogram
Answer:
Global warming occurs a result of human activities which affects the environment negatively . It usually occurs over a long period of time. The global warming causes climate changes as a result of the ozone layer depletion.
If society took the threat of global warming seriously there will be changes in how humans handle the environment and the resources. Carbon emissions would be greatly reduced. Forest resources such as trees would also be treated specially and there would have been a reduction in mass deforestation as a result of urbanization
The Tyndall Effect is the effect<span> of light scattering in many directions in colloidal dispersion, while showing no light in a true solution. This </span>effect<span> is used to determine whether a mixture is a true solution or a colloid.
Therefore, Tyndall Effect is not a process used to identify compounds.

Answer:
Explanation:
We shall apply Arrhenius equation which is given below .
![ln\frac{k_2}{k_1} = \frac{E_a}{R} [\frac{1}{T_1} -\frac{1}{T_2} ]](https://tex.z-dn.net/?f=ln%5Cfrac%7Bk_2%7D%7Bk_1%7D%20%3D%20%5Cfrac%7BE_a%7D%7BR%7D%20%5B%5Cfrac%7B1%7D%7BT_1%7D%20-%5Cfrac%7B1%7D%7BT_2%7D%20%5D)
K₂ and K₁ are rate constant at temperature T₂ and T₁ , Ea is activation energy .
Putting the given values
![ln\frac{5.9}{1} = \frac{39500}{8.3} [\frac{1}{298} -\frac{1}{T_2} ]](https://tex.z-dn.net/?f=ln%5Cfrac%7B5.9%7D%7B1%7D%20%3D%20%5Cfrac%7B39500%7D%7B8.3%7D%20%5B%5Cfrac%7B1%7D%7B298%7D%20-%5Cfrac%7B1%7D%7BT_2%7D%20%5D)
![.000373= [\frac{1}{298} -\frac{1}{T_2} ]](https://tex.z-dn.net/?f=.000373%3D%20%5B%5Cfrac%7B1%7D%7B298%7D%20-%5Cfrac%7B1%7D%7BT_2%7D%20%5D)
T₂ = 335.27 K
= 62.27 °C
