Physical Change:
*Milo dissolves into hot milk
*A plate is dropped and shatters
*Grass in mowed
*Metal Knife is sharpened
*Breakfast Cereal goes soggy
Chemical Change:
*Wood burns to form black charcoal
* A green tomato ripens and turns red
* Fireworks explode to form colourful light and loud sounds
* Vegetables scraps in the compost bin decompose to form rich soil
* An egg is cooked to become a white and yellow solid

There are several examples of chemical changes. Ten are the rusting of iron, burning of wood, metabolism of food, mixing an acid and a base, cooking an egg, mixing baking soda and vinegar, digesting sugar, baking a cake, electroplating a metal, and using a chemical battery.
Combustion:
Rapid combination of a fuel with oxygen; produces heat, light, and new substances. Examples are Gas, Oil, or coal burning in a furnace
Electrolysis:
Use of electricity to break a compound into elements or simpler compounds. Examples are breaking down water into hydrogen and oxygen.
Oxidation:
Slow combination of a substance with oxygen. Examples are rusting of an iron fence.
Tarnishing:
Slow combination of a bright metal with sulfur or another substance, producing a dark coating on the metal. Example is tarnishing of brass.
Hydrogen and oxygen react to give water.
2H2(g) + O2(g) -----> 2H2O(g)
Sodium hydroxide and hydrochloric acid neutralize each other.
NaOH(aq) + HCl(aq) -----> NaCl(aq) + H2O(l)
Sodium reduces water.
2Na(s) + 2H2O(l) -----> 2NaOH(aq) + H2(g)
Sodium chloride and silver nitrate undergo double displacement.
NaCl(aq) + AgNO3(aq) -----> NaNO3(aq) + AgCl(s)
Mercury(II) oxide decomposes to elements.
2HgO(s) -----> 2Hg(l) + O2(g)
Copper(II) is reduced by zinc metal.
CuSO4(aq) + Zn(s) -----> ZnSO4(aq) + Cu(s).
Methane combusts in oxygen.
CH4(g) + 2O2(g) -----> CO2(g) + 2H2O(g)
Sulfur trioxide reacts with water.
SO3(g) + H2O(l) -----> H2SO4(l)
Quicklime reacts with water.
CaO(s) + H2O(l) -----> Ca(OH)2(s)
Calcium carbonate decomposes.
CaCO3(s) -----> CaO(s) + H2O(g)
The three main types of chemical changes are inorganic, organic and biochemical changes. Chemical changes occur when a substance combines with another to form a new substance.
a) change in color
b) production of gas
c) formation of a percipitate
by cutting the fruits
Temperature, solid, color, gas
what are 10 examples of chemical change
These are physical and chemical changes.
The two types are chemical and physical changes.
chemical changes form to completely different things so yes
Chemical Change and Physical Change
These chemical changes are the consequence of a chemical reaction.
There are four different types of organization changes. The changes are: strategic, structural, process- oriented and people- centered.

mechanical weathering
Atoms of different elements unite during chemical changes to produce at least one chemical compound.
