What is the oxidation state of an H atom in H 2 in the equation 2 N a C l ( a q ) + 2 H 2 O ( l ) H 2 ( g ) + C L 2 ( g ) + 2 N a O H ( a q ) ? What is the oxidation state of Cr in K_2Cr_2O_4?
In a chemical combination, the oxidation number of an element indicates the number of electrons lost (if the number is positive) or gained (if the number is negative) by an atom of that element in the compound. The oxidation number is zero if the element does not loose or gain any elect...
What is the oxidizing agent of this oxidation - reduction reaction? \\ N_2(g) + 3H_2 (g) \rightarrow 2 NH_3 (g) What is the oxidizing agent? In the reaction 3Ca + 2CrBr3 arrow 3CaBr2 + 2Cr, what is the oxidizing agent?
These oxidation numbers are useful in determining whether a chemical reaction is an oxidation-reduction reaction. When we find that the oxidation state of an element changes, an oxidation reduction reaction occurs. An oxidation reaction is characterized by the loss of electrons while a reduction react...
How life on Earth began remains an unexplained scientific problem. This problem is nuanced in its practical details and the way attempted explanations feedback with questions and developments in other areas of science, including astronomy, biology, and p
In light of the performance and simplicity of chromates for corrosion protection, it is clear that replacements are not only needed, but will also ideally be required to meet acceptable anti-corrosion performance (which is now industrially expected and will also be demanded by consumers who have ...
What is an oxidation state? What do redox reactions do? Which of the following species CANNOT function as an oxidizing agent? A. Cr_2O_7^{2-} B. MnO_4^- C. NO_3^- D. S E. I^- Are all halogens oxidizing agents? Define oxidizing power in chemistry ...
The simplest substance is an element itself. Each element has a certain form and phase in which it will exist at the standard state. Metals will generally exist as solids, while non-metals may exist as solids, liquids, or gases. The form of the element at this state may not necess...
In a redox reaction, two opposite processes occur simultaneously: (1) release of electrons by a species (oxidation) and (2) gaining of electrons by another species (reduction). Answer and Explanation:1 A species is said to be reduced if its oxidation number d...
