Answer: Hurricane is not a man-made environmental change.
Explanation:
Changes which take place naturally in the environment without any force or work done by man towards causing that change are called non-man made environmental changes.
For example, hurricane is a natural environment change because a hurricane is formed moist and warm air above water surface of sea, oceans or rivers begin to rise.
This rising air is replaced by the cooler air present in the atmosphere. The continuation of this process leads to the formation large clouds and thunderstorms which occurs in the form of hurricane.
Whereas pollution is caused by vehicles driven by man, from chimneys of factories etc. So, it is a man-made environmental change.
Chemical spill can occur due to mishandling by man in laboratories or chemical labs.
Deforestation also occurs by man as they cut the trees for various needs to theirs.
Thus, we can conclude that hurricane is not a man-made environmental change.

Explanation:
hope this helps! :D
It will be the Displacement method
1 mole ----------- 6.02x10²³ molecules
? moles ---------- 3.4x10²³ molecules
(3.4x10²³) x 1 / 6.02x10²³ =
3.4x10²³ / 6.02x10²³ => 0.564 moles of H2SO4
The vapor molecules have greater KE than the liquid ones have. That"s how they break free of the liquid and waft away.
