Is reacts with acid to from H2 a phsical property or a chemical property?
Reacting with acid to form H2 is a chemical property, as it involves a change in the chemical composition of the substance. Physical properties, on the other hand, pertain to characteristics like color, density, and state of matter.
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.
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.
What is the chemical formula for hydrogen molecule?
H if you're talking about its natural form, it would be H2
What is the formula for hydrogen molecule?
Hydrogen is a diatomic element, so the formula would be H2.The chemical symbol is H, but hydrogen usually appears as H2.
Is reacts with acid to from H2 a phsical property or a chemical property?
Reacting with acid to form H2 is a chemical property, as it involves a change in the chemical composition of the substance. Physical properties, on the other hand, pertain to characteristics like color, density, and state of matter.
Is reacts with acid to from h2 physical property or chemical property?
This reaction is chemically: acid (2H+) is converted tohydrogen (H2) by picking up 2 electrons from a reactive metal. This metal is changed to an ionic salt compound.
Reacts with acid to form h2 is physical or chemical property?
This is a chemical property. When a substance reacts with an acid to form hydrogen gas, it indicates a chemical change is occurring at a molecular level, resulting in the formation of new substances with different properties.
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 electricity seperateing water into h2 and o2 a physical or chemical change?
This is a chemical change. Chemical reactions are chemical changes.
Why is mixing hydrochloric acid and sodium a chemical change?
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
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.
Why is it chemical when water is separated into o2 and h2?
It is a chemical change (reaction) because the chemical composition of the products (O2 and H2) is different from the chemical composition of the water (H2O).
What is the chemical formulae of hydrogen?
H2
What is the chemical formula for hydrogen molecule?
H if you're talking about its natural form, it would be H2
Is a salt getting formed a chemical change or physical change?
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
What process would you use to separate chemicals in a compound?
Separating compound means Decompostion or Analysis Reaction Various Chemical Decopose my various meas for eg AgCl →light→ Ag + Cl2 CaCO3 →heat→ CaO + CO2 H2O →Electricity→ H2+O2 H2O2 →MnO2(Catalyst)→ H2 + O2 There are other various reaction. There is no specific Process to Decompose Chemical compound into its Constituent.
