What is a chemical property of the element hydrogen?
Hydrogen burns in air, usually with a loud pop.
When hydrogen burns in chlorine gas it is a physical or chemical change?
Chemical, producing hydrogen chloride which when added to water produces hydrochloric acid.
What chemical product is made when hydrogen burns?
Hydrogen chloride (HCl). It is commonly known as hydrochloric acid.
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.
Hydrogen burns with a pop?
yes, hydrogen gas burns with a pop!
What is the chemical that is formed when hydrogen burns in air?
Water.
What is a chemical property of the element hydrogen?
Hydrogen burns in air, usually with a loud pop.
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
When hydrogen burns in chlorine gas it is a physical or chemical change?
Chemical, producing hydrogen chloride which when added to water produces hydrochloric acid.
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.
What chemical product is made when hydrogen burns?
Hydrogen chloride (HCl). It is commonly known as hydrochloric acid.
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.
Hydrogen burns with a pop?
yes, hydrogen gas burns with a pop!
Why do flames rise?
Hydrogen should not burn with a blue flame. Hydrogen burns clear. There must be another chemical involved.
Is hydrogen toxic to humans?
in pure quantities, yes. in general atmosphere, no.
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
