1. Combining the elemental gases, Hydrogen and Oxygen, to form the compound: water.
2H2↑ + O2↑ → 2H2O.
2. Combining Sodium hydroxide (a base) with Hydrochloric acid to form the 2 compounds: sodium chloride (a salt) and water.
NaOH + HCl → NaCl + H2O.
3. Combining Bismuth metal with Hydrochloric acid, in the presence of Oxygen, to form the 2 compounds: Bismuth trichloride (a salt) and water.
4Bi + 3O2 ↑+ 12HCl → 4BiCl3 + 6H2O
4. Combining Bismuth metal with liquid Bromine to form the compound: Bismuth tribromide (a salt).
2Bi + 3Br2 → 2BiBr3
5. Combining Sodium metal with water to form the compound: Sodium hydroxide, (a base), and releasing elemental Hydrogen gas.
2Na + 2H2O → 2NaOH + H2↑
6. The rusting of Iron, The natural combining of iron with oxygen to form the compound:
4Fe + 3O2↑ → 2Fe2O3
Physical changes: melting of ice, boiling water, crushing a soda can, breaking a glass.
Chemical changes: rusting of iron, burning wood, fermenting grapes to make wine, baking a cake.
iron rusting
baking a cake
burning paper
bleaching your hair
soured milk
here's a start for you... anything involving a fire = chemical change anything involving a hammer pounding something = physical change
Melting, evaporating, dissolving, breaking, bending, stretching, shrinking,
A physical change occurs when some of the properties of a material change, but the substances in the material remain the same.
1. candle burning
2. milk spoiling
3. digestion
4. fermentation of sugar
5. mixing vinegar and baking soda
Physical changes: melting, freezing, vaporization, condensation, sublimation.
Chemical changes: oxidation, thermal degradation, polymerization, corrosion, fermentation.

A physical change is a change in appearance or state of matter without altering the chemical composition. Examples include cutting paper or melting ice. A chemical change results in the formation of new substances with different chemical properties. Examples include burning wood or rusting iron.
Grilling a burger is a chemical change because the proteins and fats in the meat undergo chemical reactions when exposed to heat, leading to the formation of new compounds that give the burger its characteristic flavor and color.
No, chemical reactions involve changes in the chemical composition of substances, while physical changes involve changes in the physical state or appearance of a substance without altering its chemical composition.
Physical change with water: freezing water into ice (solidifying) and boiling water into steam (vaporizing). Chemical change with water: electrolysis of water to produce hydrogen and oxygen gases, and water reacting with sodium metal to form sodium hydroxide and hydrogen gas.
Physical and chemical changes both involve a transformation in matter. However, physical changes do not alter the chemical composition of substances, while chemical changes result in the formation of new substances with different chemical properties.
give examples of physical and chemical change
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
give me 50 physical changes and 10o chemical change
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
explosion of fireworks,cooking an egg
no, a physical change
this is my homework just give the answer already!
A physical change is a change in appearance or state of matter without altering the chemical composition. Examples include cutting paper or melting ice. A chemical change results in the formation of new substances with different chemical properties. Examples include burning wood or rusting iron.
1. Burning of paper 2. Vulcanizing of paper
Chemical : cooking (not heating [especially in the microwave]). Physical : making ice cubes.
There are quite a few examples of physical change including melting ice. You can also consider freezing water and boiling water a physical change.
