word equation and then balanced equation for the reaction taking place when
Answers
Answer:
The chemical reaction are the reaction in which the 2 or more then 2 reactants combines to form two or more than two products with new properties other then the properties of reactants .
The chemical reaction are of 4 types
1)Decomposition reaction →single reactant spilt into two or more then two product .
△
Ex :
magnesium oxide heat→magnesium +oxygen
2 mgo. →2mg + O²
2) Combination " "→Two or more reactants combines to form a single product
Ex:
oxygen + hydrogen →water
O² + 2 H²→ 2H²O
3) Displacement reaction →a reaction in which one element takes place of the another element in a compound.
Ex:
Copper sulphate +zinc→zinc sulphate + Copper
CuSO⁴(aq) + Zn(s)→ ZnSO⁴(aq) + Cu(s)
5) Double displacement reaction :
A reaction in which two compound reacts by exchanging of ions y form two new compounds.
Ex :
Silver nitrate + sodium →Silver chloride + sodium nitrate
AgNO³(aq ) + NaCl(aq )→AgCl (s) + NaNO³(AQ)
