On the left hand side of the equation, there are 6 hydrogen atoms and 2 nitrogen atoms. On the right hand side of the equation, there are 6 hydrogen atoms and 2 nitrogen atoms. They are both equal so the equation is balanced.
Answer:
1.Accuracy
2.Acceptance
Explanation:
1. The first advantage is Accuracy. Using meters gives us a far more precise unit of measurement because of the exact scale of reading whereas hands and steps are more of approximate methods as they may not be as accurate as the using meter due to lack of exact scale of reading.
2. The second advantage is Acceptance. Usage of meter as a unit of measurement of length is now a widely accepted unit of measurement whereas, hands and steps are not widely accepted due to their approximate nature as compared to the exact nature of metres.
The broad definition of chemistry is the study of the matter and how substances interact with energy’s and its mostly about science in high level.
Answer: Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field.
