When hydrogen burns in chlorine gas it is a physical or chemical change?
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
Is hydrogen burning a physical or chemical 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.
Is does not react with hydrogen a physical or chemical change?
This is a chemical property of an element. It indicates how an element interacts with other substances. In this case, the element does not undergo a chemical change when exposed to hydrogen.
Is producing heat chemical or physical change?
Producing heat is usually a physical change because it does not involve the formation of new substances. Heat is often a result of changes in energy levels or motion of particles in a system, rather than a chemical reaction that creates entirely new molecules.
IS bees creating wax from sugar a physical or chemical change?
The process of bees creating wax from sugar is a physical change. It involves the physical transformation of the sugar molecules into wax molecules without any change in the chemical composition of the substances.
If strontium reacts with water is it chemical or physical change?
Strontium reacts with water producing strontium hydroxide and hydrogen gas. This is a chemical change.
Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, chemical change.
Is a reacts with an acid to from hydrogen physical or chemical?
chemical change

Dissolution of hydrogen chloride gas in water is a physical change or chemical change?
It is a chemical change ....
Is a sugars and oxygen in the muscles producing lactic acid physical or chemical change?
This is a chemical change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is it a chemical change physical change chemical property or physical property when hydrogen chloride is a gas at room temperature.?
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Is hydrogen burning a physical or chemical 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.
