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).

What is the difference between physical and chemical change give examples?
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 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.

What does physical and chemical change have in common?
A physical change to an object is a change in properties not involving the chemical makeup. In other words, a physical change is any change you can make to an object without changing the actual substance. (I.e. state of matter, size, shape, color . . .etc.) A chemical change is a change that forms a new substance through a chemical reaction. A chemical reaction is often signaled by bubbling or fizzing, but the only real way to prove a chemical reaction is by coming up with a new substance. So physical changes leave you with the same substance (slightly altered in appearance/texture etc.), but chemical reactions give you a new substance.
