To determine whether each reaction is a chemical or physical reaction, we need to consider the characteristics of each type of reaction:
1. **Chemical Reaction**: Involves the formation of new substances with different properties from the reactants. This is indicated by color changes, gas production, temperature changes, or the formation of a precipitate.
2. **Physical Reaction**: Involves changes in state or appearance but does not produce new substances. Examples include changes in physical state (solid to liquid) or size without altering the chemical composition.
Unfortunately, without specific details or descriptions of the reactions mentioned (reaction 1, reaction 2, and reaction 3), I am unable to classify them as chemical or physical reactions.
For the statement about reactants A and B:
"If reactants A and B are mixed together under suitable conditions, then a chemical reaction will occur, producing new substances called products."
This statement can generally be considered **True** when conditions are appropriate for a reaction to take place, resulting in the formation of new chemical products. However, keep in mind that not all mixtures necessarily result in a chemical change; sometimes they can simply form a mixture (a physical change).
Please provide details about each reaction for accurate classification.
