Methane is burned with air in a continuous steady-state combustion reactor to yield a mixture of CO2, CO and water. The reactions taking place are

CH4 + 1½O2 → CO + 2H2O

CH4 + 2O2 → CO2 + 2H2O

The feed to the reactor contains 7.8 mol % CH4, 19.4 mol % O2, and 72.8 mol % N2. The percentage conversion of methane is 90.0% and the gas leaving the reactor contains 8 mol CO2/mol CO. How do i calculate the molar composition of the product stream using: Molecular and atomic balances and extent of teactions?

Methyl orange is an indicator with a Ka of 10^(-4). Its acid form HIn is red, while its base form In- is yellow.At pH 6.0, the indicator will be (yellow <= correct answer)I don’t understand why this is the correct answer. Here is my understanding, please correct me where I am incorrectWe know that – log Ka = pKa.Therefore, – log (10^(-4)) = 4.Therefore pKa =4.pH = pKa at half-equivalence point, so at half equivalence pt, the pH is four.At equivalence point, we have the same amount of acid and base). Therefore, 2 * half equivalence point = equivalence point. For our problem, 2*4=8, therefore 8 is our equivalence point. So, at a pH of 6, a pH of 6 < a pH of 8, therefore, according to my logic, the indicator would be red because we would not have reached equivalence point yet, and the solution would still be acidic. But my logic is obviously incorrect, so please help me find out where I am wrong. Thanks.

Metro city planners proposes that a company conserve its water supply by replacing all the community’s toilets with low-flush models that use only 2 liters per flush. Assume that there is about 1toilet for every 3 person,that existing toilets use an average of 15 liters per flush, that a toilet is flushed on average 14 times per day, and that the cost to install each new toilet is $150. write a program that would estimate the magnitude (liters/day) and cost of the water saved based on the community’s population
