Acid precipitation is caused by the release of pollutants such as sulfur dioxide and nitrogen oxides when fossil fuels are burned. These pollutants combine with water in the atmosphere to form acids, which can fall to the earth as precipitation.
The statement in the question is True. Acid precipitation can indeed be traced back to the burning of fossil fuels. When we burn fossil fuels like coal, oil, and gas, they release pollutants into the atmosphere. These pollutants include sulfur dioxide and nitrogen oxides, which can combine with water in the atmosphere to form sulfuric acid and nitric acid. These acids can fall to the earth in the form of precipitation, such as rain, snow, or fog, hence the term 'acid precipitation'. This process can have harmful impacts on the environment, including pollution of bodies of water and damage to vegetation.

Answer:
The correct option is;
Scientist propose explanations that can be explained by examining evidence
Explanation:
A scientists makes an hypotheses based on possible natural processes to explain the origin and/or the nature of the characteristics of a natural observation. The scientist then source more data and information to put their hypotheses to test. Due to the fact that an hypotheses is based on observable processes and/or mechanisms, the given hypotheses can be further tested by other scientists through the use of their individually sourced data. From the result of the assessment, the hypotheses can be either accepted or rejected to enable the better clarification of the hypotheses when accepted or the development of a new hypotheses when rejected.

C) 1.67g
D) 3.33g
Answer:
Taiga
Explanation:
The volume of one mole of gas at STP is 22.4 liters.
In the combustion reaction of acetylene (C2H2), 60 liters of CO2 will be produced if 60 liters of O2 is used.
To determine the volume of CO2 produced in the combustion reaction of acetylene (C2H2), we need to use stoichiometry. From the balanced equation, we can see that 2 moles of C2H2 produce 4 moles of CO2. The ratio is 2:4 or 1:2. Given that 60 liters of O2 is used, we can assume the same volume of CO2 will be produced since both gases are at STP.
Therefore, the volume of CO2 produced would be 60 liters as well.

increases to 100 times the original concentration
decreases to 1/100 of the original concentration
decreases to 1/2 of the original concentration
Answer: The correct answer is 'increases to 100 times the original concentration'.
Explanation:
let the initial pH be x
The original concentration of initially present be y
...(1)
Final concentration of when pH reduced by 2 be z
...(2)
Putting the value of 'x' from (1) into (2) we get :
When pH of a solution decreases by 2.0, hydronium ion concentration of the solution increases to 100 times the original concentration
Answer:
B, is the answer
