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:

What is the difference between physical and chemical change give examples?
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.
Is grilling a burger a chemical or physical change?
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.
Can chemical reactions have physical changes?
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.
Give you 2 examples of physical and chemical change with water?
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.
What does physical and chemical change have in common?
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.
Alternate Wordings for 'What is chemical change and physical change and give its examples?
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.
Is sieving most useful?
Sieving is useful for separating particles of different sizes and is commonly used in industries like agriculture, construction, and pharmaceuticals. It is especially effective in filtering out impurities or unwanted solids from a mixture. However, its utility depends on the specific application and the properties of the materials being processed.
