1955 Robert Wentorf. Graphite to diamond at 2000°C and 106 atm. Even though graphite is more stable than diamond at 25°C and atmospheric pressure, the conversion is very slow. A process called chemical vapor deposition uses Carbon sources like methane to release carbon atoms in presence of hydrogen gas and deposit it as diamond at low pressure and temperature (600°C) Reference: Chemistry: An atoms first approach, Zumdahl & Zumdahl, Cengage Learning, 2012. Question: Based on the above phase diagram: Comparing graphite and diamond, which one is denser? How many triple points? Explain

Chemistry I (Science Majors) (CHEM-141... Ć Malachite is a green copper mineral with the formula Cu₂CO3(OH)2. It can be converted into copper metal in a number of ways. One method extracts the metal by reacting the malachite with sulfuric acid to form CuSO4, and then adding iron to the CuSO4 solution which, after they react, forms FeSO4 and copper metal. The balanced chemical reactions are: Cu₂CO3(OH)2 (s) + 2 H₂SO4 (aq) →2 CuSO4 (aq) + 3 H₂O (1) + CO₂ (g) CuSO4 (aq) + Fe (s) →FeSO4 (aq) + Cu (s) If the final solution is dried, and 3.28 g of iron sulfate is collected, how many grams of malachite were originally used?

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.
