Which of the following describes the cause of acid rain?
taurus [48]

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

what is the empirical formula for a compound that is 50.61% copper 11.16% nitrogen and 38.23% oxygen
jonny [76]

Answer:

CuNO3

Explanation:

In order to calculate the empirical formula in this question;

Cu = 50.61% = 50.61g

N = 11.16% = 11.16g

O = 38.23% = 38.23g

Next, we convert each gram unit to moles by dividing by their respective molar mass (Where; Cu = 63.55, N = 14, O = 16)

Cu = 50.61 ÷ 63.55 = 0.796mol

N = 11.16 ÷ 14 = 0.797mol

O = 38.23 ÷ 16 = 2.389mol

Next, we divide each mole value by the smallest (0.796)

Cu = 0.796mol ÷ 0.796 = 1

N = 0.797mol ÷ 0.796 = 1.001

O = 2.389mol ÷ 0.796 = 3.001

Approximately, the simple whole number ratio between Cu, N and O is 1:1:3, hence, the empirical formula is CuNO3.
