A chemist needs to make a buffer at a pH of 4.5. 600 mL of 60MM acid is prepared. pka of acid=4.81 Molar mass of salt: 198.11 g/mol h) what mass of this salt should be added to

Here is a graph of the pressure of ethylene (C₂H₂) in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below. atm 30- 25- 20.870 15- 10+ 5+ 50 100 150 seconds Is C₂H4 being created or destroyed by the chemical reaction? If C₂H4 is being created or destroyed, what is the rate at which it is being created or destroyed 100 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If C₂H4 is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 100 seconds of the reaction? 200 Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 250 created destroyed 300 neither created nor destroyed 0 X 00 0.0 Ś

Eats PI L la To determine the stability of kinetomycin, a pharmacist dissolves an unknown amount of the drug in one litre of a saline solution. Samples are then taken at various times and sent to lab 10p allalysis. The following data are reported by the lab. Time (hr) Amount (mg) 3.5 3. Zero-order; because of a straight line on a semilog graph. 4. Zero-order; because of a straight line on a linear graph. 2. Which of the following statements is CORRECT for a ZERO-ORDER process? 1. The rate is independent of the amount or concentration of the drug. 2: The half-life is independent of the amount or concentration of the drug. 3: The rate constant is dependent on the amount or concentration of the drug. 4: The unit of rate constant is 1/time. 521 6.5 445 I. Please answer the following two multiple choice questions: 1. Please plot the above data on both linear and semilog graphs. What is the order of degradation process of kinetomycin? Why? 1. First Order; because of a straight line on a…
