If you would like to get your goals, keep this in mind! the following are one of the answer and question example that you could make use of to practice and upgrade your understanding and also give you insights that can assist you to maintain your study in school.
Question:
Which equation represents a conservation of atoms?
Answer:
Answer:
4) 4Fe + 3O₂ → 2Fe₂O₃
Explanation:
4Fe + 3O₂ → 2Fe₂O₃
In this equation the numbers of atoms are same in both side. There are four iron and six oxygen atoms are present on left and right side of equation. That’s why atoms are conserved. This equation completely followed the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
From the answer and question examples above, hopefully, they might assist the student deal with the question they had been looking for and take notice of each thing stated in the answer above. You will be able to then have a discussion with your classmate and continue the school learning by studying the problem as a group.
