Acid rain can form in a two-step process, producing HNO3(aq). N2(g) + 202(g) → 2NO3(g) 3NO2(g) + H2O(g) → 2HNO3(aq) + NO(g) a. A car burns 420. g of N according to the above equations. How many grams of HNO will be produced?
b. For the above reactions to occur, O must be in excess in the first step. What is the minimum amount of O needed in grams?
c. What volume does the amount of O in part b occupy if its density is 1.4 g/L?​

Problem page gaseous ethane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water . if of water is produced from the reaction of of ethane and of oxygen gas, calculate the percent yield of water. be sure your answer has the correct number of significant digits in it.

Listenbase your answer to the question on the information below. nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body. cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment. which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
