This is a chemical change.
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Oxygen and hydrogen
Boiling hydrogen sulfide is a physical change, as it is a reversible process where the substance changes from a liquid to a gas due to the absorption of thermal energy. The chemical composition of hydrogen sulfide remains the same during boiling.
Strontium reacts with water producing strontium hydroxide and hydrogen gas. This is a chemical change.
Yes, the combination of hydrogen and oxygen to form water is a chemical change. In this reaction, new bonds are formed and energy is released, resulting in a new substance with different properties than the original elements.
This is a chemical change.
Dissolving in water is a physical change.
The formation of water from oxygen and hydrogen is a chemical change because new chemical bonds are formed between the atoms to create a new substance with different properties than the original elements.
No, it is not.
No.
Easy, chemical change.

When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
