What are some advantages and disadvantages to the acid rain management techniques?
mr_godi [17]

• Acid rain affects the fresh water ponds and lakes and destroys the aquatic life as some species of fishes are rare and may be extinct
• it can affect the trees particularly those that are high altitude
• It can damage historical monuments and buildings
•soil can be affected and can lead to deaths of good microbes

Advantages of acid rain:
• it makes holes in limestone below ground, which creates caves and places to store groundwater, as well as providing habitat for some species
• But the new study shows that sulfuric in acid may have benefits, limiting global warming by counteracting the natural production of methane gases by microbes in wetland areas.

Of course you should do more studying on acid rain but these are the simple ones

pishuonlain [190]

Answer:

Therefore 373 mole of Al produce 746 mole of water.

Explanation:

Given reaction is

3 Al+3NH₄ClO₄→Al₂O₃+AlCl₃+3NO+6H₂O

From the above reaction it is clear that 3 mole of Al produce 6 mole of water.

Therefore

3 mole of Al produce 6 mole of water.

1 mole of Al produce \frac{6}{3} mole of water.

373 mole of Al produce \frac{6\times 373}{3} mole of water.

                                      = 746 mole of water.

Therefore 373 mole of Al produce 746 mole of water.
