Dissolving in water is a physical change.
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 the condensation of oxygen gas a chemical change or physical change?
It is a physical change.
Is oxygen a chemical change or a physical?
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
Reaction with oxygen is a physical or a chemical change?
Oxidation is a chemical process.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is the condensation of oxygen gas a chemical change or physical change?
It is a physical change.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is oxygen a chemical change or a physical?
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
Is burns in the presence of oxygen physical or chemical change?
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
Reaction with oxygen is a physical or a chemical change?
Oxidation is a chemical process.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
Distinguish between physical and chemical change?
A chemical change is a change involving making and breaking chemical bonds to form new chemicals. For example when wood burns the carbon and hydrogen in the cellulose react with the oxygen in the air, forming carbon dioxide and water. A physical change is one that the chemical changes states and no new chemicals are formed, like melting ice or dissolving salt in water.
Is burning a log a example of chemical or physical changes?
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Is a sugars and oxygen in the muscles producing lactic acid physical or chemical change?
This is a chemical change.
