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.
Explanation:
this is a single Replacement Reaction, so Na and Cl will form a bond.
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.
