Answer 1

element + element =compound

or you could say

2 or more elements

Answer 2

A compound can be identified by analyzing its physical and chemical properties, conducting spectroscopic analysis (e.g., infrared spectroscopy, nuclear magnetic resonance), and using techniques such as mass spectrometry to determine its molecular weight. Comparing the compound's data with known standards or databases can help in its identification.
