Which of the following metal is the best material selection combination for the nitric acid environment? Correct Answer Stainless steels

Stainless steels are the best combination of metal for the nitric acid environment. Stainless steels readily form a passive oxide film in nitric acid. This minimizes or reduces the corrosion damage.

Solution-1 containing 10% nitric acid and 20% acetic acid at the rate F combines with Solution-2 containing 20% nitric acid and 10% acetic acid at the rate D, the product formed contains 30% nitric acid and 20% acetic acid at the rate P, how many independent equations containing F, D, and P are possible?
In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.

Acid rain is any form of precipitation with high levels of nitric and sulfuric acids. It can also occurs in the form of snow,fog and tiny bits of dry materials that settle on the ground. rotting vegetation and erupting volcanoes release some chemicals that causes acid rain but majority is because of the human activities such as burning of fossil fuels, factories and auto mobiles. Acid rain has many ecological effects, few of which are given below. Which of the following, if true, would weaken the conclusion about the effects of acid rain on the environment? 
Which statement is correct about strong acid? Statement 1: An acid that is completely ionized in water and thus produces a very small amount of hydrogen ions is called a strong acid.  Statement 2: Sulphuric acid and nitric acid are also strong acids.
