What evidence is there to show that a chemical reaction has taken place when an egg is cooked?
The change in color indicates that a chemical reaction has taken place.
Is an indicator's reaction in acids and bases a chemical or physical change?
The indicator's reaction in acids and bases is a chemical change because it involves a change in the chemical structure of the indicator molecule due to its interaction with the ions present in the acid or base solution. This results in a change in color, which is a visible manifestation of the chemical reaction taking place.
What identifies a chemical change has taken place?
Signs that a chemical change has taken place include the formation of a gas, the formation of a precipitate, a change in temperature, and a change in color.
What are the ending materials in a chemical reaction called?
The ending materials in a chemical reaction are called products. These are the substances that are formed as a result of the chemical reaction taking place.
What is the name of the type of reaction taking place in Q2?
The type of reaction taking place in Q2 is hydrolysis. Hydrolysis is a chemical reaction where water is used to break down a compound into its constituents.
What is one fairly certain indication that a chemical change is taking place?
color
Why do experiements change color?
because of the chemical changes taking place between the atoms involved...
The color of gold physical or chemical?
The color of gold is a physical characteristic, determined by its interaction with light and the way it reflects and absorbs different wavelengths. It is not a result of any chemical reaction taking place.
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 an example of a color change that does not indicate a chemical reaction?
Many materials can change colour according to the temperature without there being any chemical reaction taking place.
What is the chemical process taking place in the plant to manufacture carbohydrates called?
wat is the chemical process taking place to manufacture cabohydrates called
Is fire transparent?
Fire is not transparent. It emits light and has a color due to the chemical processes taking place during combustion. The color of fire can vary based on the temperature and the materials burning.
How do you know that a chemical reaction is taking place?
You can tell a chemical reaction is taking place if there is a change in color, temperature, formation of gas bubbles, or the production of a precipitate. Additionally, if the reactants are transformed into new substances with different properties, a chemical reaction has likely occurred.
What energy is taking place Sunlight into electricity?
chemical
The indicator in a test tube change colour orange to yellow what process is it?
This change in color indicates a chemical reaction taking place in the test tube. The specific reaction that caused the color change would depend on the substances present in the test tube and their chemical properties.
The chemical change taking place when food is cooked is?
