What else can I help you with?
Which one is not a sign of a chemical change change in shape bubbling smoking changing color?
Changing shape is not typically a sign of a chemical change. Chemical changes involve the rearrangement of atoms and molecules to form new substances with different properties. Shape change is more likely a physical change.
Is baking a physical or chemical change?
pretty sure its a chemical change.
What is a sign of a reaction oh a chemical change?
a colour change, a gas produced or a precipitate (new substance/solid) formed.
Is it true that Physical changes are often accompanied by changes in color or odor?
No, a chemical change is usually accompanied by a change in color or odor. A physical change is a change that is the same substance before and after and usually accompanied by a change in state of matter (evaporation, condensation, melting, freezing, sublimating, etc).
Why is only one sign of a chemical change not enough to guarantee a chemical change has occurred?
To avoid a confusion with other processes. Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
What is one sign of a chemical change?
Change of color

If the color changes it is a chemical or physical?
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
Is the color of a copper wire a physical property or chemical property?
Color is a physical property. However, change in color is a sign of a chemical reaction.
A change in color when two solutions are mixed together is a clue that what has taken place?
A change in the color of a solution is a sign thatthere is a chemical change happening. A chemical change happens when two substances combine forming another substance. It can also happen when two or more substances decompose.
Is baking a physical or chemical change?
pretty sure its a chemical change.
Is a common sign that a chemical change has occurred?
A change in pH or conductivity will always hint to a chemical change. Also less technical signs can be a change in volume or color
A change in color of an indicator is a sign of that?
A colour change in a chemical indicator implies that a distinguishable chemical property has been changed in the given system.
What is the sign of a chemical change?
The sign of a chemical change can include the formation of a precipitate, a color change, the emission of gas bubbles, a change in temperature, or the evolution of light or heat. These observable indicators can signify that a chemical reaction has taken place.
Whoch of the sign of a chemical change woums you see at a campfire?
There is a few signs of a chemical change that you see in a campfire. You can tell by the color, temperature and burning.
When could color change be a result of a physical change?
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
What is the most likely sign that a chemical change has happened?
The most likely sign that a chemical change has occurred is the formation of a new substance with different properties. This can include color changes, formation of a precipitate, evolution of gas, or changes in temperature.
