When iron is immersed in a solution of hydrochloric acid hydrogen gas is produced a physical or chemical property?
This is a chemical reaction.
Is combining hydrogen and oxygen to make water physical?
This is a chemical reaction.
Why is a silver platter tarnishing a physical property?
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
Is it a chemical or physical reaction?
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
Is absorbency a chemical or physical property?
Scientists make a distinction: physical absorption (without chemical reaction) and chemical absorption (involving a chemical reaction).
When iron is immersed in a solution of hydrochloric acid hydrogen gas is produced a physical or chemical property?
This is a chemical reaction.
Is reacts with acid to form H2 a chemical or physical properties?
This is a chemical property, as it involves a chemical reaction where hydrogen gas is produced when the substance reacts with an acid. Physical properties refer to characteristics such as color, state, density, and boiling point.
Is iron dissolving in hydrochloric acid with the evolution of hydrogen gas a physical property?
No, this is a chemical property. When iron dissolves in hydrochloric acid, it undergoes a chemical reaction in which the iron atoms lose electrons and form iron(II) chloride, while hydrogen gas is evolved. This is a chemical change, not a physical change.
Is combining hydrogen and oxygen to make water physical?
This is a chemical reaction.
When sodium is put into waterit react forming sodium hydroxide and hydrogen is this physical change or chemical change?
That's most definitely a chemical change, because new forms of matter are produced. Before the reaction, you had pure sodium and water. After the reaction (which is very explosive by the way), you have sodium hydroxide and hydrogen gas.
When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
Is reaction of hydrogen chloride gas and water a physical change or chemical change?
The reaction of hydrogen chloride gas and water is a chemical change because new substances are formed, specifically hydrochloric acid. Chemical bonds are broken and formed during the reaction.
Substance produced by a chemical reaction?
A product is a substance formed during a chemical reaction. It is the result of the reaction's course and might have different physical or chemical properties than the reactants.
When steam passes through hot iron what substances are produced after chemical reaction?
Fe3O4 and Hydrogen gas
What are elements or compounds produced by a chemical reaction?
products are produced after a chemical reaction.
A glowing splint placed in a test tube causes a loud pop Is this chemical or physical change?
The loud pop indicates a chemical change. The glowing splint caused a reaction that produced a gas (likely oxygen or hydrogen) leading to the noise. This transformation is a result of a chemical reaction and not just a physical change.
Is combining hydrogen and oxygen to make water is a physical?
No.
