Breaking glass is an example of a physical change because if you break it, it is still glass.
Answer: The bond formed between the elements will be ionic bond.
Explanation: We are given two elements having electronic configurations:
Element 1:
Element 2:
Element 1 can easily loose 1 electron to attain stable electronic configuration and Element 2 can accept 1 electron to attain stable electronic configuration.
For these elements, there will be a complete transfer of electron from Element 1 to Element 2. Hence, this will form a ionic bond.
From the configuration, Element 1 is Lithium and Element 2 is Fluoride. So, the compound is LiF.
The equation N2+H2= NH3 is balanced. This is because N2 + 3H^2 ➡️ 2NH^3
The answer is A, to my brain power ig B)
