You can't really "create" a chemical. You can process chemicals into other chemicals, but there are a great many different ways to do this and you'd need to be a lot more specific about what you want and what you have available in order for us to begin to answer it.
chemical
Yes, chemical reactions can create new molecules and compounds by rearranging atoms in existing substances. This process involves breaking and forming chemical bonds to create different combinations of elements.
No.
Distillation.
In and of itself, no. Both chemical and physical changes can create bubbles.
The importance of a chemical bond is to create molecules. So matter is larger.
No.
Electrical energy out of chemical energy.
Salt
No they do not create. Chlorophyll convert energy,light energy into chemical energy
Salt (sodium chloride) and iodine do not create a chemical reaction when combined. They can be physically mixed together to form a mixture, but they do not undergo a chemical transformation.
No, you just create a mixture with more components.
