Answers
Answer:
★ Chemical reaction
when a new substance is formed in a reaction it is known as chemical reaction
Explanation:
♦ Types Of Chemical Reactions
♠ Combination Reaction
→ Two or more reactants combine to form a single product
eg : C + O2 = CO2
♠ Decomposition Reaction
→ Single reactant breakdown to form two or more product
eg : ZnCO3 = ZnO + CO2
♠ Exothermic Reaction
→ In which heat is liberated
eg : CaO + H2O = Ca(OH)2
♠ Endothermic Reaction
→ In which heat is absorbed
eg : 2HgO + heat = 2Hg + O2
♠ Displacement Reaction
→ More reactive metal displaces a less reactive metal
eg : Fe + CuSO4 = FeSO4 + Cu
♠ Double Displacement Reaction
→ Different ions in reactant molecules are displaced by each other
eg : 2KBr + BaI = 2KI + BaBr2
♠ Oxidation Reaction
→ Addition of oxygen or removal of hydrogen
eg : 2Mg + O2 = 2MgO
♠ Reduction Reaction
→ Removal of oxygen or addition of hydrogen
eg : CuO + H2 = H2O + Cu
♠ Redox Reaction
→ Oxidation and reduction takes place simuntaneously
eg : CuO + H2 → H2O + Cu
