Acid rain is produced from CO2, NO????, and SO???? dissolving in atmospheric water molecules. This causes a decrease in the pH o
1 answer:
Explanation:
When emission of industrial gases like sulfur dioxide, carbon dioxide and nitrogen oxide combine with water then the rain that consists of these acids fall into the atmosphere is known as acid rain.
When these gases combine with water then they result in the formation of an acid that is present in an aqueous phase.
So, when sulfur trioxide combines with water then the reaction will be as follows.
Hence, we can conclude that sulfuric acid is formed when sulfur trioxide gas reacts with water.

Answer:
3.65 x 10¹⁰ electrons
Explanation:
we'll apply the following equation for electric field of a point charge on a spherical conductor
where E is the electric field
k is a constant of the value 8.99 x 10⁹ Nm²/C²
r is the radius of the spherical conductor
q is the total charge in the sphere
Given diameter d =41.0cm, radius r = 20.5cm = 0.205m (convert cm to m)
Electrical field E = 1250 N/C
we are asked to determine how many excess electrons must be added to the surface of the sphere to produce this electric field
q = <u>E x r²</u>
k
q = <u>1250 N/C x 0.205m</u>²
8.99 x 10⁹ Nm²/C²
q = 5.84 x 10⁻⁹ C
this is the total charge in the sphere
To determine the number of electrons, we can divide the charge q by the charge on an electron e (1.6 x 10⁻¹⁹C)
n = <u>5.84 x 10⁻⁹ C </u>
1.6 x 10⁻¹⁹C
n = 3.65 x 10¹⁰ electrons
Therefore, to apply an electric field of magnitude 1250 N/C, the isolated spherical conductor must contain 3.65 x 10¹⁰ electrons
