Question

3) Explain why rain is naturally acidic, but not all rain is classified as “acid rain." 9) Here are examples of what an individual might do to reduce acid rain. For each, explain the connection to production of acid rain. a. avoid running a washing machine with a small load b. add additional insulation on a home hot water heater c. walking instead of driving to work

Can I please get help with question 8 and 9 please.

Answer 1

Acidity is measured using a scale called the pH scale. pH=below 7: Acidicin nature pH=7.00: Neutral pH=Above 7: basicin nature pH of wateris 7 because of neutral in nature. Rain water is acidicin nature because, presence of CO, (in atmosphere),it converts into carbonicacid. The chemical reaction is as follows: Co,+H,0–>H,CO, The ability of H.CO to deliver Htis what classifies this molecule as an acid, thus lowering the pH of a solution. HACO, *H*+HCO Nitric oxide (NO), which also contributes to the natural acidity of rainwater, is formed during lightning storms by the reaction of nitrogen and oxygen two common atmospheric gases In air. N,+O, — 2NO. The formed NO is oxidized to nitrogen dioxide (NO2). The chemical reaction is as follows:NO+O, — →NO NO, reacts with water to give nitric acid, which deliver H*, thus lowering the pH of a solution. --- --------- ---- ----- ---- ---- ----- ---- ---- ----- ---- ----- --- - Especially nitrogen oxides and sulphur dioxide react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds lowering the pH of a solution. – which is why it is known as "acid rain".

As per HomeworkLib rules i should have to answer only one question per post so please ask remaining post in another post.
