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?
is when the solid is hard then the word is Melting to change to liquid
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.
A change in matter which doesnt change the individual molecules?
A change in matter that does not change the individual molecules is a physical change. During a physical change, the substance retains its molecular structure but undergoes a change in properties such as shape, size, or state (solid, liquid, gas). Examples include melting, freezing, dissolving, and phase changes.
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.
Is water freezing at 0C a physical or chemical change?
Water freezing at 0°C is a physical change. This process involves a change in the state of matter from liquid to solid without altering the chemical composition of the water (H₂O). The molecular structure remains the same; only the arrangement and energy of the molecules 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.
Why is freezing cooking oil a physical change?
Freezing cooking oil is a physical change because it involves a change in the state of matter from liquid to solid without altering the chemical composition of the oil. When cooled, the oil's molecules slow down and come together to form a solid structure, but the molecular structure remains the same. This process is reversible; the oil can be returned to its liquid state by warming it up. Thus, no new substances are formed during freezing.
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.
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.
Does the molecular structure of water change due to the movevent in rivers?
No
Is freezing a water a physical change?
Because the structure remain the same.
