Is milk sours a example of physical change?
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.
What kind of physical evidence might be observed what would indicate that chemical reaction occurred?
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 chemiluminescence -formation of new compounds
Reaction with oxygen is a physical or a chemical change?

Is iron that rusts in moist a physical property chemical property physical change or a chemical change?
Rusting is a chemical process, an oxidation reaction.
Is an indicator's reaction in acids and bases a chemical change?
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.
What are indicators of a chemical change when 2 substances are mixed together?
Some indicators include:Change in TemperatureChange in ColorNoticeable Odor (after reaction has begun)Formation of a PrecipitateFormation of BubblesWhen two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Proceed with caution.
Is dissolving a physical or chemical reaction?
a physical reaction for the chemical structure is not changing.
What is made from a chemical reaction?
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.

Is water a chemical reaction or a physical reaction?
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
Is oxidizing Mercury physical or chemical change?
Both. A chemical reaction occurs & a physical change is noticeable.
