What is the oxidation number of Cr in Cr2O72 is?
The oxidation number of Cr in Cr2O7^2- is +6. This is because the overall charge of the dichromate ion is 2-, and each oxygen atom has an oxidation number of -2. By setting up and solving an equation representing the total charge of the ion, we can determine the oxidation number of Cr.
What is the oxidation number of Cr2O72?
The oxidation number of Cr in Cr2O7^2- ion is +6. Each oxygen atom has a -2 charge, and the overall charge of the ion is 2-, so combining the charges gives -2*(-7) = -14. Since the overall charge is 2-, the oxidation number of Cr must be +6 to balance the charges.
What is the oxidation number for Cr in Cr2O3?
+6 for Cr, -2 for each O in Cr2O72-oxidation number for oxygen is -2 so 7 of them makes -14 in total but the compound has an overall charge of 2- so therefore +12 is required. As there are two chromium then the oxidation number for each one is +6
What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
What is the oxidation number of Cr in Cr2O72- is?
The answer is + 6 The way I figured it out was that O has a -2 charge. -2 times 7 is - 14. to leave -2 you need a +12 charge. So you divide 12 by 2 because you have 2 Cr and you get 6
What is the oxidation number of Cr in CaCrO4?
+2 for Ca, +6 for Cr, -2 for each O
The oxidation number of sulfur in H2 SO4 is?
The oxidation number of sulfur in H2SO4 is +6. This is because hydrogen has an oxidation number of +1 and oxygen has an oxidation number of -2, so by the rules of oxidation numbers, sulfur must have an oxidation number of +6 to balance the equation.
In CaSO4 the oxidation number of Ca is that of S is and that ofO is?
In CaSO4, the oxidation number of Ca is +2, the oxidation number of S is +6, and the oxidation number of O is -2.
What is the oxidation number of sulphur in caso4 so4s02s03?
For CaSO4 (calcium sulfate), the oxidation number of sulfur is +6. For SO4 (sulfate ion), the oxidation number of sulfur is +6. For SO2 (sulfur dioxide), the oxidation number of sulfur is +4. For SO3 (sulfur trioxide), the oxidation number of sulfur is +6.
What is the oxidation number for 6H?
The oxidation number for hydrogen (H) is typically +1. Therefore, the total oxidation number for 6 hydrogen atoms would be +6.
What is the oxidation number for Cr in MgCrO4?
The oxidation number of Cr in MgCrO4 is +6. This is because oxygen is typically assigned an oxidation number of -2, and the overall charge of the compound is 0, so the oxidation number of magnesium (+2) and oxygen (-2) must be balanced by the oxidation number of Cr (+6).
Why the oxidation number of sulphur is plus 6?
Sulphur has 6 valence electrons. So its maximum oxidation number is +6.
