If a substance changes color what has most likely happened chemical or physical change?
Very probable a chemical change; but also physical changes can be the cause.
Which of the following is the most likely a sign that a chemical change has happened?
D.Two liquids are mixed at room temperature and a gas forms.
Which chemical change is most likely to involve bubbling or an odor?
A chemical change that is most likely to involve bubbling or an odor is the reaction between an acid and a base to produce water and a salt. For example, mixing hydrochloric acid (HCl) with sodium hydroxide (NaOH) produces water and sodium chloride (NaCl), with bubbling and a characteristic odor of the products.
A substance is giving off heat light and smoke Most likely the type of change that is occurring is?
Chemical change, as it involves a chemical reaction that results in the formation of new substances with different properties.
Is mixing two substances and light is produced a chemical or physical change?
If light is produced when two substances are mixed, it is most likely a chemical change. Chemical changes involve the formation of new substances with different properties, whereas physical changes typically only affect the state or appearance of a substance without altering its chemical composition.

What is most likely sign that a chemical change has happend?
The most likely signs of a chemical change include the production of gas (bubbles or odor), color change, temperature change (heat or light released), and the formation of a precipitate (a solid that forms from a solution). These indicators suggest that new substances have been created as a result of the chemical reaction.
What observations give that a chemical reaction has happened?
is the colour change, tempeture change ,gas produced the most common ones

Is burning leaves a physical or chemical?
It is a chemical change anytime you burn something it will most likely be chemical change because something new comes out, for example when you burn the leaves you will get ash which is something the leaves did not have before! your welcome!:)
Is growing vegetables physical or chemical?
Growing vegetables can be a chemical process. However it is most likely that growing vegetables is a physical process because the chemical composition does not usually change.
