What is the difference between a chemical reaction and physical change?
The difference between them is that in a chemical reaction, the chemical make up of the substance put into the experiment is changed or modified. In a physical change, only the physical attributes of the substance is changed, like size, shape, color, density, etc.
Is a Decay of fallen leaves a physical or chemical change?
chemical because the chloroplast have had the chlorophyll die off
Is mold a chemical change?
No. A material is heated, i.e. changes state, then hardens again. No chemical change, but at least a partial state change.
Is a change in state an indicator of a chemical reaction?
It is a change in physicalness
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
How can you tell the difference between a chemical reaction and not a chemical reaction?
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials
Difference between a pysical change and a chemical change?
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.
What is the chemical difference between the gaseous and liquid state of the same substance?
Any chemical difference exist.
Is there a chemical difference between the gaseous state and liquid state of a substance?
Phase has nothing to do with chemical composition.
Difference between chemical and physical changes?
a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.
What is the difference between Chemical vs physical change?
A physical change is when something changes to a different state (solid, liquid or gas), but it does not change chemical composition; for example, it remains H2O. In a chemical change, new chemical bonds are formed.
What is the main difference between physical change and chemical change?
Physical changes do not make new substances and can be reversed. Chemical changes create new substances and are very difficult to reverse.
What is the difference between a chemical reaction and physical change?
The difference between them is that in a chemical reaction, the chemical make up of the substance put into the experiment is changed or modified. In a physical change, only the physical attributes of the substance is changed, like size, shape, color, density, etc.
Are there observable similarities between physical and chemical change?
Well obviously, a physical change and a chemical change both envolve changing of state
What is the difference between phyical and chemical changes?
A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
Is a Decay of fallen leaves a physical or chemical change?
chemical because the chloroplast have had the chlorophyll die off
Is mold a chemical change?
No. A material is heated, i.e. changes state, then hardens again. No chemical change, but at least a partial state change.
