By definition, a chemical change is anything that changes the chemical properties of a substance. So, if any substance chemically changes, such as a piece of burning wood, a rusting pan, or a burnt piece of toast, that is a chemical change.
Chemical changes are happening all the time. There are several different types of chemical change, including: synthesis, decomposition, single displacement, double displacement, neutralization, precipitation,combustion and redox. Whenever chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium hydroxide and hydrogen chloride to produce sodium chloride, or table salt. This reaction is so exothermic, meaning it releases heat in the form of energy, that even flames are generated. This is an example of a chemical change because the end product is molecularly different from the starting molecules.

How do you know if somethings chemical change or physical change?
In a chemical change, a new substance is produced. For example, if something is burnt, it is no longer what it originally was and is, therefore, a chemical change. A physical change is a change in appearance: shape, quantity, and form of matter (solid, liquid, gas).

What does not signal a chemical change color change or production of light and heat or production of gas or change in state?
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.

State why there is a brief delay in the transmission of an impulse across the synapse?
The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.
