<u>Answer:</u>
2400 mL
<u>Explanation:</u>

According to this equation, the stoichiometric ratio between
and
for the complete reaction is 1:2.
We know that the number of moles of
can be calculated using the mole formula. (<em>number of moles = mass / molar mass</em>)
Moles of Calcium =
= 1.5 mol
So the moles of
=
= 3.0 mol
<em>Volume of HCl solution = Moles of HCl/ concentration of HCl</em>
Volume of HCl solution =
= 2400 mL
The cooling of a mint is just a sensation if you were to put mints into warm water the water would remain warm because it is just a cooling sensation. I hope this helps:)
Disadvantages of acid rain:
• 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
