</span>2. When an atom loses electrons, it becomes <span>positively charged because its protons outnumber its electrons. ( In an atom, number of protons = number of electrons, when electrons are lost, the number of protons >the number of electrons.)</span>
Answer:
The possible source of errors as regard the Procedure are:
- The final temperature was measured before the temperature stopped changing
- The cap of the calorimeter was not closed immediately after mixing
- temperatures where not measured right before mixing
Explanation:
The procedure referred to should a experiment with regards heat
The possible source of errors as regards the Procedure are:
- The final temperature was measured before the temperature stopped changing
- The cap of the calorimeter was not closed immediately after mixing
- temperatures where not measured right before mixing
The answer is 197
Hope I helped
