WebThe correct option is A Cr2O3+2Al Δ −→ Al2O3+2Cr. More electropositive element displaces less electropositive element. Cr2O3+2Al Δ −→ Al2O3+2Cr. Reaction (a) and (d) are decomposition reaction. Reaction (c) is a single displacement reaction but it does not displace a metal. Hence, option (b) is the correct answer. Suggest Corrections.

WebRedox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Some examples of common redox reactions are shown below. WebSolution Step 1. Write a sceleton equation Step 2. Separate the redox reaction into half-reactions a) Assign oxidation numbers for each atom b) Identify and write out all redox couples in reaction c) Combine these redox couples into two half-reactions Step 3. Balance the atoms in each half reaction a) Balance all other atoms except H and O
WebRedox reaction: Redox reaction means a reaction in which oxidation and reduction takes place simultaneously. In reaction N 2 + 3 H 2 → 2 NH 3, here H 2 is getting oxidized with rise in oxidation state from 0 to + 1 and N 2 is getting reduced with decrease in oxidation state from 0 to-3. Therefore, this is an redox reaction. WebChemistry Worksheets Class 11 on Chapter 8 Redox Reactions with Answers - Set 4. A redox reaction is a chemical reaction that transfers electrons between two reactants. This electron transfer can be identified by the change in the oxidation states of the reacting species. Fuel combustion, metal corrosion, and even photosynthesis and cellular ...
