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.
What product is formed when hydrogen burns the air?
When hydrogen burns in air, it forms water (H2O). This is a chemical reaction in which hydrogen gas (H2) reacts with oxygen gas (O2) to produce water vapor.
What chemical product is made when hydrogen burns?
Hydrogen chloride (HCl). It is commonly known as hydrochloric acid.
What is a chemical formula a molecule of hydrogen that is made up of two atoms of hydrogen?
The chemical formula for a molecule of hydrogen made up of two atoms of hydrogen is H2.
Which compound is made of hydrogen and oxygen?
Two compounds are made of hydrogen and oxygen. Water has the chemical formula H2O, and hydrogen peroxide has the chemical formula H2O2.
What is the chemical that is formed when hydrogen burns in air?
Water.
When hydrogen burns in air the change is chemical Give two reasons to support this assertion?
When hydrogen burns in air with H2+O2= H20

Is the sun made of chemical composition or material?
Our Sun is mainly Hydrogen, which it burns via Fusion into Helium.To consider further, have a crack at nucleosynthesis in an online encyclopedia.
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
What is a chemical formula a molecule of hydrogen that is made up of two atoms of hydrogen?
The chemical formula for a molecule of hydrogen made up of two atoms of hydrogen is H2.
Which compound is made of hydrogen and oxygen?
Two compounds are made of hydrogen and oxygen. Water has the chemical formula H2O, and hydrogen peroxide has the chemical formula H2O2.
What is pure water and write its chemical formula?
H2O A compound formed when hydrogen gas burns with oxygen.
Is formation of water when hydrogen burns a chemical change or a chemical property?
It's a chemical change. Any time you have a change in the chemical formula of a substance, you have a chemical change. The chemical formula of hydrogen is H[2], and the chemical formula of oxygen is O[2]. The chemical formula of water is H[2]O. 2 H[2] + O[2] --> 2 H[2]O. If you were watching this happen in a lab, you'd watch two colorless gases react to form a single colorless liquid. A change in state (solid, liquid, or gas) that cannot be due to heating or cooling is nearly always a sign of a chemical change.
What is a chemical property of the element hydrogen?
One chemical property of hydrogen is its ability to react with oxygen to form water. Hydrogen also exhibits the property of being highly flammable when exposed to air or an oxygen-containing atmosphere.
