WebChromium exists in nature primarily in one of two oxidation states. There are other chemical oxidation states of chromium, which include 0, II, IV, and V, but they are considered transitory compared to more stable Cr(III) and Cr(VI) species. Hexavalent chromium is a strong oxidizer which can react with DNA causing mutation, while the trivalent, how many gfci outlets in seriesWebApr 3, 2024 · It is written as C r O 4 2 −. The charge on the chromate ion is -2. The oxidation state of chromium in chromate ion is +6 and the oxidation state of oxygen is -2. There are four oxygen atoms, so we have to multiply -2 with four to get -8. By adding the oxidation state of chromium and total oxidation state of oxygen, we get -2. how many gfci outlets can be on one circuitWebSolution. First, compute the volume of chromium that must be produced (equal to the product of surface area and thickness): volume = ( 0.010 mm × 1 cm 10 mm) × ( 3.3 m 2 × ( 10,000 cm 2 1 m 2)) = 33 cm 3.
