Which masses of carbon (C) and hydrogen (H) could be used to form a substance with the empirical formula CH? C: 92.258 g; H:7.742 g

C: 11.071 g; H: 0.929 g

C: 36.903 g; H: 3.097 g

All the above masses of C and H could form a CH compound.

About 8 gallons of fuel will be used. (8.08)

The answer should be vaporization 

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
