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↑

CHEMICAL CHANGE: Such change is a permanent change and substances go through such changes not only alter their outer shape but also change their composition. For example: conversion of milk into yoghurt is a chemical change PHYSICAL CHANGE: Such change is a temporary change and substances go through such changes alter their shape and volume only but composition remains same. For example: water changes into ice and ice melt to water is a physical change.
Is turning glow sticks on a chemical or physical change?
It is a chemical change because when you shake it and crack it, chemicals are released that give off a glow.
What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
Can chemical reactions have physical changes?
Physical changes do not change the kind of matter or its properties. Ex. cut a piece of paper and you sill have paper. Chemical changes cause the atoms to recombine and form new substances with different properties. Ex. burn wood, it isn't wood anymore, it is ash and smoke and heat energy. ASH wasn't there before burning.
