What else can I help you with?
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
Is combining hydrogen and oxygen to make water is a physical?
No.
Is combining water and salt physical or chemical change?
Dissolving in water is a physical change.
What is a physical change that takes place when oxygen and hydrogen are combined to form H2O?
When oxygen and hydrogen combine to form water there is a chemical change, not a physical change. That may be followed by a physical change, depending on the conditions when the chemical change occurs. You may, for example begin with water vapor and, if the temperature is low enough, it will condense (a physical change) to liquid water.
Which is only a physical change?
A physical change is something that does not change the chemical makeup of a substance. For example, water turning into vapor is a physical change because the composition is not changed. Water vapor still has hydrogen and oxygen just like water.
What kind of changes are melting and freezing?
Melting, freezing, boiling, evaporation are physical change
Example of a physical rather than a chemicalchange?
Which of the following is an example of a physical rather then a chemical change? Which of the following is an example of a physical rather then a chemical change?
Is recycling paper an example of a physical or chemical change?
physical change physical change
Provide an example of a physical change?
An example of physical change is ice melting in to water.
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.
