  1. Irreversible reactions are permanent and cannot be undone. For example, burning wood. When you burn wood you get ash and smoke. You cannot change the ash and smoke back to wood.

  2. An irreversible change is when you cannot make it back, like if you burn paper into ashes, you can't change ashes into paper back again. However, if you freeze water you an melt it and change it back into water again. Two examples of irreversible changes are when you make a mixture of a cake and form it into a cake you can't change it back, the next example is when you fry an egg you can't change it back into an egg.

  3. An irreversible reaction is something that happens that you cannot change back. An example is a balloon popping. As you can't un-pop a balloon.

  4. An irreversible reaction means when you cant bring it back into its original state. An example is that if you boil an egg you cant make it into its original state.Arya

  6. a inverseble reaction is when an object cant turn back into themselves. For example if you spill water on box it will be all soaky and defintly not been used again.

  7. An irreversible reaction is when a reaction can not be reversed.An example is cutting a carrot.once you cut it you can not put it back together.

  8. A irreversible reaction is when a reaction can't be reversed.An example is that if you mix soap and water it goes all frothy and you can't change that

  10. A fundamental concept of Science is that chemical reactions occurred when reactants reacted with each other to form products. These unidirectional reactions are known as irreversible reactions, reactions in which the reactants convert to products and where the products cannot convert back to the reactants. These reactions are essentially like baking. The ingredients, acting as the reactants, are mixed and baked together to form a cake, which acts as the product. This cake cannot be converted back to the reactants (the eggs, flour, etc.), just as the products in an irreversible reaction cannot convert back into the reactants. by mushtq

  11. In a irreversible reaction, the reactants react to form the products, which cannot revert back into reactants. In reversible reactions Example ice cream (lolly pop).

  12. An irreversible reaction is when changes takes place and you can not return it back to its original state. Example: when you pop a popcorn. You can not turn back popped corn into kernels or normal corn again because it is already popped.

  16. Mixing substances can cause an irreversible change. For example, when vinegar and bicarbonate of soda are mixed, the mixture changes and lots of bubbles of carbon dioxide are eventually made. These numerous numbers of bubbles, and the liquid mixture left behind, cannot be turned back into vinegar and bicarbonate of soda again.

  17. An irreversible reaction is when a reaction can't be reversed. one example is that you can't unary bacon.

  18. An irreversible reaction is when something can not be changed after doing it once. For example coco cola and mentos . BY MISHCA

  19. it is a reaction that can not be reversed for example if you mix carrot and vinegar it will pickle and that's irreversible

  20. An irrevsible reaction is when you make a mixture and then you can't revers it end more.
    Example: egg and heat if you heat up a egg and then you cool it down it will not tern back into a raw egg.

  21. Irreversible reaction means something that cannot change back to its original self. An example is pizza as it cannot change back to its original self.

  22. a irreverable object is when yu can not change it back when it reacted,blown up or dissolved e.g a burger it has been eaten and slowly digested.

  23. One irriversable change is when you mix bananas with sprite and also an example for a reversible change is if you have metal and you melt it it will be liquid but when it hardens.

  24. An irreversible reaction is when two or more components are mixed and cannot be put back to their original state after the reaction. For example mixing sugar with tea (sugar will dissolve within the tea and can not be removed) or baking a cake (after mixing all ingredients and baking the cake, ingredients used cannot be bought back to its original form or get separated after its baked).

  25. An irreversible means that when it reacts and that can not be reversed.For an example you cut the cake then you can not start again.

  26. a irreversible reaction is when you mix two things together and you cant turn it back into its orignal from.for example you mix
    suger and water you can not turn it back
