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
Does copper have chemical or physical?
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
Is h20 a physical or chemical property?
H20 is a chemical property because it refers to the chemical formula for water, which consists of two hydrogen atoms bonded to one oxygen atom. This composition describes the specific arrangement of atoms in a water molecule, which is a characteristic of its chemical identity.
What determines the physical properties of minerals?
The physical properties of minerals are determined by their chemical composition and atomic structure.
Are physical properties of hydrogen peroxide except?
Physical properties of hydrogen peroxide include being a colorless liquid, having a slightly sharp odor, and being miscible with water.
Is hydrogen is a colourless gas chemical or physical?
Hydrogen is a colorless gas, and this characteristic is a physical property. Physical properties describe the appearance and state of a substance without altering its chemical composition. In contrast, chemical properties involve the reactivity and behavior of a substance during chemical reactions. Therefore, the colorlessness of hydrogen is a physical aspect of the gas itself.
Why does water not have the same physical and chemical property then hydrogen and oxygen?
Because molecules have other chemical and physical properties than the containing atoms !
Is reacting with oxygen a physical property of hydrogen?
No, reacting with oxygen is a chemical property, not a physical property, of hydrogen. Physical properties are characteristics that can be observed without changing the substance's chemical composition, such as density or color. Chemical properties, on the other hand, describe how a substance can change or react to form new substances.
Why do water and hydrogen peroxide have the same chemical and physical properties?
They both are made of hydrogen and oxygen. Has 2 H bonds among molecules. They have a few different properties too.
Is hydrogen chemical or physical property?
Hydrogen is neither a chemical or physical property...it is a chemical element.
All atoms of hydrogen have the same chemical and physical properties?
No some can be very strong like lightning
Is displaces hydrogen from an atom a physical or chemical property?
Displacing hydrogen from an atom is a chemical property, as it involves a chemical reaction that results in a change in the substance's composition and properties. Physical properties, on the other hand, are those that can be observed or measured without changing the substance's chemical composition.
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.
Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Is hydrogen a chemical or physical property?
Hydrogen is a chemical property because it is a pure substance and it cannot be broken down into simpler substances by physical means. It is the simplest and most abundant chemical element in the universe.
Are the physical and chemical properties of HCl different from those of H2 and Cl2?
Yes, HCl is a compound formed by the reaction of hydrogen and chlorine, so it has different properties from its constituent elements H2 (hydrogen gas) and Cl2 (chlorine gas). HCl is a polar molecule with acidic properties, while H2 and Cl2 are nonpolar molecules with different reactivity and chemical characteristics.
