A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.

What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
What chemical reaction that can proceed forward or backward is a?
You think probable to a reversible reaction.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
The reaction in which two or more substances react to form a single substance?
A synthesis reaction or dehydration synthesis, also called a condensation reaction.
What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
What reaction is opposite of a synthesis reaction?
It would be a catabolic reaction or decomposition reaction.
Why initial reaction is required to minus from final reaction?
The initial reaction is required to be subtracted from the final reaction to get the net reaction.
If you have a forward reaction and reverse reaction occurring together what type of reaction is that?
reversible reaction
What are types of isolation?
Answer a.speed of the reaction. b.products of the reaction. c.pH of the reaction. d.temperature of the reaction
