The local environmental changes are having a global effect, and that is well documented and constantly witnessed. The reason why local environmental changes can have such a big impact is that the gasses move freely throughout all of the planet, they move horizontally with the winds, and they also move vertically higher into the atmosphere which is in constant movement.
This results in a situation where one area produces lot of pollution, but another area is feeling the effects because the air masses moved big portion of the polluters there.
A nice example are China and Mongolia. China is one of the two major polluters in the world, while Mongolia barely has any industry especially when considered its size and population. The air masses though are moving from the southeast towards northwest, thus big portion of the pollution in the eastern part of China goes into Mongolia. Because of this, despite not being a big polluter, Mongolia has one of the worst air qualities in the world.
Also, we can witness that the holes in the ozone layer are mostly around the poles, despite the sources of the chemicals that are damaging it are on totaly different locations.
Answer:
The balance equation is
→ 
Explanation:
first, we have to make sure that the atoms are balanced
→ 
→ 
then we proceed to balance charges of each half-reaction
→
→ 
Now we multiply the half-reactions to match the number of electrons in each one
( → )x2
( → )x3
and now we do the sum of the half-reactions
2
→ 2
→ 3 
→
note: the only atom that needed to be balanced was I
Answer: 2.3 moles
Explanation:
Recall that based on Avogadro's law, 1 mole of any substance has 6.02 x 10^23 atoms
So if 1 mole of Aluminum = 6.02 x 10^23 atoms
Then, Z moles = 1.4 x 10^24 atoms
To get the value of Z, we cross multiply:
1 mole x 1.4 x 10^24 atoms = Z x (6.02 x 10^23 atoms)
1.4 x 10^24 atoms = Z x (6.02 x 10^23)
Hence, Z = (1.4 x 10^24 atoms) ➗ (6.02 x 10^23 atoms)
Z =2.3 moles
Thus, there are 2.3 moles in 1.4 x 10^24 atoms of aluminum.
Hey there!
No !! there is nothing to react. What else other than tin sulphate and zinc sulphate can you make - but then you have only what you started with .
Hope that helps!
