When drain cleaner is added to water bubbles of hydrogen are produced Is what happens to form the bubbles when the cleaner is added a chemical or physical reaction?

If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.

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.
Is boiling water a chemical or physical process?
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
Why is a silver platter tarnishing a physical property?
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
Is color a physical or chemical reaction?
Physical reaction.

This is a chemical reaction.
Is Ag tarnishes physical property or chemical property?
It is a chemical process - a reaction with hydrogen sulfide.
Is reaction of hydrogen chloride gas and water a physical change or chemical change?
It's a chemical change
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 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.
Is boiling water a chemical or physical process?
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
Is hydrogen a reactants?
Hydrogen can be a reactant or a product, it depends on the chemical reaction. Anything to the left of the arrow is consumed by the reaction and is thus a reactant, so hydrogen is a reactant in the reaction O2 + 2H2 -> 2H2O. A product is on the right of the arrow and is produced by the reaction, so hydrogen is a product in the reaction Zn + 2HCl -> ZnCl2 + H2
Is luster a chemical or physical or chemical reaction?
Luster is a physical property or reaction.
Why is a silver platter tarnishing a physical property?
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
