The unbalanced chemical equation with the corresponding phase for each substance is shown below:
Cu₍s₎ + H₂SO₄₍aq₎ → CuSO₄₍aq₎ + SO₂₍g₎ + H₂O₍l₎
The copper metal is solid, the sulfuric acid and copper sulfate are in aqueous solution. Water is in the liquid phase while sulfur dioxide is in the gas phase.
In order to obtain the balanced equation, we must ensure that the number of atoms present in the reactant side is equal to that in the product side. First, we list the elements involved and count their number on each side.
Reactant Product
1 Cu 1
2 H 2
1 S 2
4 O 5
To balance the equation, we need to have 2 moles of H₂SO₄ and 2 moles of H₂O. The balanced chemical equation is then:
Cu₍s₎ + 2H₂SO₄₍aq₎ → CuSO₄₍aq₎ + SO₂₍g₎ + 2H₂O₍l₎
Reactant Product
1 Cu 1
4 H 4
2 S 2
8 O 8
28.0 x 0.6424 = 18
25.0 x .6424 = 16.1
Mass = 34.1
Answer: Acid rain.
Explanation:
According to some experts, acid precipitation can lead to acid rain. Acid rain is a product of chemical reactions caused by the release of compounds such as sulfur dioxide and nitrogen oxides into the air. These substances can form in the atmosphere itself and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
There are specific theories that nitrogen oxides cause acid rain, in other sulfur oxides, which are produced by the combustion of coal or petroleum products, for example, in thermal power plants, automobile engines, and plants for the production and purification of metals. With water vapor, they produce nitric or sulfuric acid, respectively. This natural disaster is very bad for flora and fauna, it has a particular negative reflection on forests and the aquatic world, especially fish.
the algal population will decrease.
Answer:
For example, 0.9% NaCl contains 0.9 g NaCl per 100 ml of solution or 9 g NaCl/l. This can be converted to molarity by dividing by molecular weight: 0.9% NaCl = (9g/l)/(58.5g/mole) = 0.15 M NaCl.
