Next, the following equation describes the polynomial curve to the [SO₂Cl₂] versus time data was received: [SO₂Cl₂] = 4.93 × 10-8 t² - 1.16 × 10-4 t +9.90 × 10-² Which of the following equation describes best the first derivative of the best fit curve: d [SO₂Cl₂] dt d [SO₂Cl₂] dt d [SO₂Cl₂] dt Od [SO₂Cl2] dt (a) at 200 min: i (4.93 × 10-8)t - 1.16 × 10−4 = 2(4.93 × 10−8)t – 1.16 × 10−4 + 9.90 × 10-² 2(4.93 × 10-8)t – 1.16 × 10-4 = : (4.93 × 10−8)t – 2(1.16 × 10−4) Calculate slope of the tangent of the first derivative. Use scientific notation, e.g. enter 2E3 for 2000. Enter your answer with one significant figure. (b) at 600 min i = M min-¹ M min -1 Finally, compare the graphically determined instantaneous rate of decomposition at 200 min (A) and at 600 min (B) to the slope of the tangent of the first derivative at 200 min (a) and at 600 min (b): The positive of the values of the slope of the tangent of the first derivative are far close identical to the graphically determined rates.

Nitroglycerine ( C,H,N,O,) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4 C,H,N,O,() → 6 N2(9) + 12 CO(9) + 10 H,0(9) + 7 O2(9) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 241 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 4o% dynamite explodes? mol gas
