a molecule having slightly negative and positive ends with regard to change
A change in the nucleotide base sequence of gene or DNA molecule is called a what?
this is called a mutation
Is a sugar cube ground up a chemical change?
If the temperature is below the decomposition temperature, then melting a physical change not chemical as the liquid sugar (or molten sugar) can be solidified again.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Liquid alcohol will change to vapor when its temperature reaches the what?
Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C
What is a chemical change but not a physical change?
Chemical change: the structure of the molecule is modified. Physical change: the structure of the molecule is not modified.
When is a phase change and when is it a sign of a chemical change?
After a physical change the molecule remain intact.After a chemical change the molecule is modified.
What is the diference between a physical change and a chemical change?
Chemical change: the structure of the molecule is chenged. Physical change: the structure of the molecule is not changed.
Why is boiling or melting a physical change and not a chemical change?
because you dont change the molecule. H2O IS THE SAME MOLECULE as water, ice or steam
What is the difference between a chemistry change and a physical change?

How is a chemical change different froma physical change?
A physical change doesn't modify the chemical nature of the molecule.A chemical change transform the molecule A in another molecule B.
What is the scientific difference between a physical change and a chemical change?

How does a physical different from a chemical change?
A physical change doesn't change the molecule of a compound.
When states of matter change so does the chemical composition of the molecule?
No, the chemical compound of the molecule doesn't change. The molecules just spread farther apart.
A molecule having slighty negative and positive ends with regard to change?
a molecule having slightly negative and positive ends with regard to change
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
