The metal whose oxide can be reduced by common reducing agents:
The metal whose oxide can be reduced by common reducing agents: (a) Copper(b) Sodium(c) Aluminium(d) Potassium Ans: (a) Copper Understanding Metal Oxide Reduction Metal oxides are compounds formed when metals react with oxygen. To extract the pure metal, the oxygen must be removed, a process known as reduction. This is achieved using a reducing agent,…
Which formula represents a saturated hydrocarbon?
Which formula represents a saturated hydrocarbon? (a) C4H8(b) C5H12(c) C4H6(d) C5H10 Ans: (b) C5H12 Understanding Saturated Hydrocarbons Saturated hydrocarbons, also known as alkanes, are characterized by having only single bonds between their carbon atoms. This means that each carbon atom is bonded to the maximum possible number of hydrogen atoms. Let’s examine why the other…
