(a) Neutralisation between strong acid and strong base e.g.,
NaOH + HCl -> NaCl + H2O + 13.7 kcal
(b) Double decomposition reactions or precipitation reactions e.g.,
BaCl2(aq) + H2SO4(aq) -> BaSO4(s) ↓ + 2HCl(aq)
(c) Thermal decomposition, e.g.,
(d) Redox reactions, e.g.,
SnCl2(aq) + 2FeCl3(aq) -> SnCl4(aq) + 2FeCl2(aq)
burning piece of wood, making curd from milk, firing cracker, rusting iron

No, though it is not easily irreversible like chemical reactions it is mainly a physical change, unless your car set in fire. (Burning is chemical)
Rusting is a irreversible change although you can get products which can get rid of it.
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
Compounds are pure chemical substances with two or more different chemical element that can be separated by chemical reactions. Examples include water compounds (oxygen and hydrogen), and table salt (sodium and chlorine).
Cooking involve irreversible chemical reactions.
irreversible
yes, because it is a chemical reaction (chemical reactions are irreversible).
chemical reactions are irreversible but physical changes are reversible
some chemical changes can be reversed but they are hard to reverse usually
Yes because it is a chemical reaction and these reactions are irreversible
Digestion involve chemical reactions, it is a chemical and mechanical process and is irreversible.
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
The reactions in which the products do not recombine to form reactants are called irreversible reactions. They are supposed to complete and are represented by putting a single arrow (-------->) between the reactants and products.
No, it isnt. There are chemical reactions while breathing.
forms
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
