Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.
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.
Is combining dry ingredients a physical or chemical change?
Combining dry ingredients is a physical change. In this process, the individual components retain their chemical identities and properties, and no new substances are formed. The change is primarily in the mixture's physical state and appearance, but the original substances remain unchanged at the molecular level.
What are the two criteria for whether a change is chemical or physical?
Oxygen and hydrogen
When Hydrogen sulfide is boiling is it a chemical or physical change?
Boiling hydrogen sulfide is a physical change, as it is a reversible process where the substance changes from a liquid to a gas due to the absorption of thermal energy. The chemical composition of hydrogen sulfide remains the same during boiling.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.
Is combining water and salt physical or chemical change?
Dissolving in water is a physical change.
Is Oxygen and hydrogen combining to form water a physical or chemical change?
The formation of water from oxygen and hydrogen is a chemical change because new chemical bonds are formed between the atoms to create a new substance with different properties than the original elements.
Is combining hydrogen and oxygen to make water is a physical?
No.
Is hydrogen and oxygen combining to form water and example of a physical change?
No, it is not.
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 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.
Is combining baking soda and vinegar a chemical change?
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
