It is impossible to run 15 miles an hour
I think
Hope this helps :D
A molecule has an empirical formula of ch, and its molar mass is known to be 26 g/mol and the molecular formula is C₂H₂ ethyne
Molecular formula of compound is (CH)n and the given molar mass is 26g/mol
Molar mass of (CH)n, C=12=n(12+1)=13n
So 13n and n=2
=13×2=26 and given molar mass is also 26g/mol
So here two carbon and two hydrogen so molecular formula is C₂H₂ and name is ethyne
Know more about molecular formula

Answer:
The protons inside an atom's nucleus help bind the nucleus together. They also attract the negatively charged electrons, and keep them in orbit around the nucleus. The number of protons in an atom's nucleus determines which chemical element it is.
Answer:
Concept: Radiology & Chemistry
- Energy waves are judged based on their wave length, which is measures from one "hump" to the next
- In order from least to greatest, aka increasing: Radio Waves, infrared waves, visible light, UV, x-Ray, and Gamma
- Give brainlist and rate positively
