Emission Factor = [5.0E-03 lbs Cr/lb Cr]*[0.3 lbs Cr+6/lb Cr] = [1.5E-03 lbs Cr+6/lb Cr sprayed] This value is between the ARB HVOF emission factor for a control device with 90% efficiency and a control device with 99% efficiency, as summarized in Table C-3. Therefore, these results are reasonably consistent with ARB’s methods. Ohio

e You can determine this by oxidation numbers, Cr is +6 on left and changes to +3 on the right, but twice thus 6e− tranferred OR you can do it by balancing the charge with the correct number of electrons. As written, the charge on left is (2−) + (14+) ≠ (6+), thus you need 6− more on the left, you can get that with 6 electrons.

Volume Cr = thickness ( surface area. Converting to cm3, Next, calculate the mass of Cr. Mass = density ( volume. Step 3: Find the number of moles of electrons required to electrodeposit 18 g of Cr from solution. The half-reaction is: Cr2O(aq) + 14H+(aq) + 12e( → 2Cr(s) + 7H2O(l) Six moles of electrons are required to reduce 1 mol of Cr metal.

For nondegree courses, Adjudication always must determine the course code from the approval form or screen and never from this list directly. Note that flight training codes are 341 through 347. When coding training taken in high school (type F) or elementary school (type L), adjudicators should use course codes 451 and 452.
