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
By Boyles Law (P1V1=P2V2), substituting values in and solving for V2, we find that the new volume is 3.6 L<span />
The name of the chemical made of 14 g Lithium or 2 moles
Lithium, 32 g Sulfur or 1 mol sulfur and 64 g oxygen or 4 moles of oxygen is
Lithium sulfate. From the chemical reation:
<span>2Li + S + 4O > Li2SO4</span>
Answer:
14.5 g silver
Explanation:
This is a problem using the stoichiometry of the reaction. First thing we need is the balanced equation:
Zn + 2 AgNO3 ----------------------- 2 Ag + Zn(NO3)2
We know that 14.6 g of Zn did not reacted, then we can calculate the amount of Zn reacted and do the calculation given the above reaction.
amount Zn reacted: 19.0 -14.6 g Zn = 4.4 g Zn
atomic weight of Zn: 65.37 g/mol
mol Zn reacted: 4.4 g Zn x ( 1 mol Zn/ 65.37 g Zn) = 0.067 mol Zn
We know from the balanced equation that moles of Ag are produced from 1 mol Zn therefore the mol of Ag produced are:
0.067 mol Zn x 2 mol Ag/ 1mol Zn = 0.135 mol Ag
and the mass of silver then will be given by multiplying by the atomic weight of silver:
0.135 mol Ag x 107.9 g/mol = 14.5 g Ag
