What evidence is there that a chemical reaction has occurred in an automobile?
Some signs of a chemical reaction occurring in an automobile could include smoke or unusual smells coming from the engine, changes in the color of liquids like oil or coolant, or the presence of corrosion or rust on metal parts. Additionally, a drop in performance or unusual noises could also indicate a chemical reaction, such as combustion in the engine.
If one substance changes color is it a chemical reaction?
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
List three signs that could make you think a chemical reaction might be taking place?
Formation of bubbles or gas: Gas evolution can indicate a chemical reaction is occurring. Change in color: A sudden change in color could be a sign of a reaction, such as a shift from clear to cloudy. Temperature change: If the reaction generates heat (exothermic) or absorbs heat (endothermic), it can be an indication that a chemical reaction is taking place.
What is the only sure way to prove that a chemical reaction has occurred?
The only sure way to prove that a chemical reaction has occurred is to demonstrate a change in the chemical composition of the substances involved. This can be done by analyzing the reactants and products using techniques such as spectroscopy, chromatography, or mass spectrometry to identify any new substances formed. Additionally, measuring physical changes such as color, temperature, gas production, or precipitate formation can also provide evidence of a chemical reaction taking place.
In which situation is a chemical reaction occurring?
A chemical reaction occurs when there is a change in the chemical composition of substances involved, resulting in the formation of new substances with different properties. Signs of a chemical reaction include the release of heat or light, formation of a precipitate, color change, or production of gas.
What are signs of a chemical reaction?
Some signs could be: *solids forming *bubbles *color change *temp. change

How could you visually tell that something is having a chemical reaction?
If you see fizzing, bubbling, or a change in color. They're good signs of chemical reactions you can see. Also, smoke. If you see smoke, you probably have a chemical reaction.
If two chemicals are added together in a beaker and the beaker gets cold is that a chemical reaction?
Not necessarily. The cooling effect could also arise from mixing chemicals that absorb heat when mixed with each other, even though they do not react. The cooling could, of course, also indicate a chemical reaction.
How do you know a reaction occurred?
A reaction has occurred when there are observable changes, such as a color change, the formation of a precipitate, the evolution of gas (bubbles), or a temperature change (exothermic or endothermic). Additionally, if the properties of the original substances change and new substances with different properties are produced, it indicates that a chemical reaction has taken place. Observing these signs can confirm the occurrence of a reaction.
What does evidence chemical change mean?
Evidence of a chemical change refers to observable signs that a chemical reaction has occurred. This can include color change, formation of gas or precipitate, temperature change, or production of light. These changes indicate that the substances involved in the reaction have undergone a chemical transformation at the molecular level.
Can a chemical reaction cause heat?
Yes, the signs of a chemical reaction are: gas, precipitation, heat, color change

The question does not have the enough required information that is required to accurately answer it.
How do we know a chemical reaction has occurred?
A chemical reaction can be identified by several observable signs: the formation of a gas (bubbles), a change in color, the production of heat or light, and the formation of a precipitate (solid) from a liquid solution. Additionally, changes in properties such as odor or taste may indicate a reaction. These indicators suggest that the original substances have transformed into new substances with different chemical compositions.
