What else can I help you with?
When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
Yes, a chemical change can still occur without a noticeable change in temperature. Some chemical reactions are endothermic (absorb heat) and others are exothermic (release heat), so observing a change in temperature is not always a reliable indicator of a chemical change taking place. Other signs to look for include color changes, gas production, formation of a precipitate, or the release of light.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Can you make ice go into a chemical change?
Water is a chemical (pretty much all matter is technically made of chemicals), so it can undergo chemical changes. Ice itself is not particularly reactive, but if it is melted into water (physical change), it can be chemically changed in a number of ways. These are some relatively common ones: 1. Water can be mixed with CO2 (Carbon dioxide) to form Carbonic Acid, something with a different chemical structure from water. 2. Water can undergo electrolysis to be split into its component elements, hydrogen and oxygen.
Is ductility a physical or a chemical change?
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.
Is axe sharpening a chemical change?
yes it is a chemical change as some part of the axe gets removed
What chemical change takes place when an iron nail rusts?
Bonds are formed between some of the iron atoms in the nail and oxygen atoms from the air.

Is hammering gold into foil a chemical or physical change?
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Indicates how likely an element is to undergo a chemical change?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
What are some What are facts about nail polish?
there is chemical's in there and it has color in it and can kill you by sniffing it a lot..
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
Is walking on snow a physical or chemical change?
Walking on snow is a physical change because the snow remains as solid ice crystals and does not undergo any chemical reactions to form new substances.
Is a hot dog is cooked a chemical chnage or a physical change?
Cooking a hot dog is primarily a chemical change. During the cooking process, the heat causes the proteins and other components in the hot dog to undergo chemical reactions, resulting in changes in flavor, texture, and color. While there may be some physical changes, such as the expansion and browning of the hot dog, the key transformations are chemical in nature.
What is the definition of chemical properties?
Chemical properties refer to the characteristics of a substance that describe its ability to undergo a chemical reaction or change into a different substance. These properties include reactivity, flammability, toxicity, and acidity/basicity.
Is a cooked hot dog physical or chemical change?
CHEMICAL:)
