Is boiling alcohol and then considering the vapor a chemical change?
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.
How does the chemical reaction of alcohol result in the formation of a colored substance?
When alcohol undergoes a chemical reaction, it can produce a colored substance due to the formation of new molecules with specific light-absorbing properties. This change in molecular structure can lead to the absorption and reflection of certain wavelengths of light, resulting in the perception of color.
Change from liquid to solid?
This process is called solidification or freezing. When a substance loses heat energy and its particles slow down enough to form a rigid structure, it changes from a liquid to a solid state.
Do microwave ovens alter molecular structure?
Microwave ovens can cause molecular changes by agitating water molecules in food, leading to heating. They do not change the molecular structure of the food itself, but can affect nutrients like vitamins and antioxidants due to heating. It's still a debated topic in the scientific community.
Is washing cloths is a chemical change?
Washing clothes is a physical change, not a chemical change. The dirt and stains on the clothes are being physically removed, but the molecular structure of the clothes remains the same.
What is an xaple of physical rather tham a chemical change?
A chemical change occurs when molecular structure is altered. Ex: oxidation A physical change is any sort of change that occurs without affecting the molecular structure. Ex: freezing
Can molecular structure of moonlight change random?
No. Light is not made of molecules and has no molecular structure to change.
What is the difference between a chemical change and a physical change in a reaction?
A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.
What is a physical verus a chemical change?
A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.Grinding is physical, neutralization of an acid is chemical.
Differenting physical and chemical change?
A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.Grinding is physical, neutralization of an acid is chemical.
What is the different between a physical and a chemical change?
A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.Grinding is physical, neutralization of an acid is chemical.
How chemical and physical change?
A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.
Does the molecular structure of water change due to the movevent in rivers?
No
If you boil ethyl alcohol does the chemical structure change?
No. The chemical structure of ethyl alcohol gas is the same as ethyl alcohol liquid.
Is freezing a water a physical change?
Because the structure remain the same.
What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
Some ways that density can change?
Pressure Temperature Changes in the molecular structure(chemical change)
