Q :4 Write difference between :
1) Oxidising & Reducing agent.
2)corossion & Rancidity
3) thermal & Photochemical decomposition.
4) Displacement reaction & Double displacement?
(if anyone gave answer i will mark them as Brainliest)
Answers
1) *Oxidising agent is an element or compound that gains an electron during redox reaction.
*Reducing agent is an element or compound that loses an electron during redox reaction.
2) *Corrosion is a process where metals are attacked by moisture and gets oxidised and wears down.
*Rancidity is the spoilage of food when the fats and oils in them gets oxidised and become unsuitable to consume.
3) *Thermal decomposition is a process where a compound breaks into simpler substance when it is exposed to heat.
*Photochemical decomposition is a process where a compound breaks into simpler substance when it is exposed to light.
4) * Displacement reaction is a reaction where a more reactive element replaces a less reactive element.
*Double displacement reaction is a reaction where a reactant exchange ions to form two new elements.
