identify each transition in this flowchart as a chemical change or a physical change. answer bank chemical physical
Answer
Explanation:
Step1: Analyze 1 - 2 transition
New molecules are formed. Chemical bonds are broken and new ones are made. So it is a chemical change.
Step2: Analyze 2 - 3 transition
No new substances are formed. Just a change in the state or arrangement of the same molecules. So it is a physical change.
Step3: Analyze 2 - middle transition
New substances are formed as the composition of molecules changes. So it is a chemical change.
Step4: Analyze middle - 4 transition
The molecules are separated into individual atoms. Chemical bonds are broken. So it is a chemical change.
Step5: Analyze middle - 5 transition
Atoms combine to form new molecules. Chemical bonds are formed. So it is a chemical change.
Answer:
1 - 2: chemical 2 - 3: physical 2 - middle: chemical middle - 4: chemical middle - 5: chemical
