Is chlorine gas liquefies at 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at 35 degrees Celsius under normal pressure is a physical change. It involves a change in the state of the substance (from gas to liquid) without altering its chemical composition.
When placed in H2O a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms chemical or physical change?
This is a chemical change. When sodium reacts with water, it undergoes a chemical reaction to produce hydrogen gas and sodium hydroxide. The formation of new substances (sodium hydroxide) and the evolution of gas (hydrogen) indicate a chemical change rather than a physical one.
Sodium metal in chlorine gas releases energy is it a physical property?
No, the release of energy when sodium metal reacts with chlorine gas is a chemical property, not a physical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties are characteristics that can be observed without changing the substance's composition.
If making ammonia from nitrogen and hydrogen A chemical or physical change?
Making ammonia from nitrogen and hydrogen is a chemical change because it involves a rearrangement of the atoms in the reactants to form new chemical compounds in the product (ammonia). This process is characterized by the breaking and forming of chemical bonds.
Is hydrogen peroxide a chemical or physical change?
Catalase breaks down hydrogen peroxide into water and oxygen. Catalase is found in blood and bacteria in the wound. The bubbles you see are from the oxygen that is being released.
Is sodium and chlorine a physical change or a chemical change?
chemical
When hydrogen burns in chlorine gas it is a physical or chemical change?
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
Is the change between sodium and chlorine a physical change or chemical?
chemical
Is reacts violently with chlorine physical or chemical?
this is a chemical change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is chlorine gas becoming a liquid a physical or chemical change?
It is a physical change because the chemical composition has not changed.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, chemical change.
Is a reacts with an acid to from hydrogen physical or chemical?
chemical change
Dissolution of hydrogen chloride gas in water is a physical change or chemical change?
It is a chemical change ....
Is reacts violently with chlorine physical or chemical property?
Reacting violently with chlorine is a chemical property because it describes how a substance undergoes a chemical change when coming in contact with another substance, in this case, chlorine.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is it a chemical change physical change chemical property or physical property when hydrogen chloride is a gas at room temperature.?
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
