Sulfur trioxide decomposes to sulfur dioxide and oxygen gas as shown in the following reaction:
2503 (g) 2502 (g) + O2 (g)
Given a 240.0 g sample of sulfur trioxide (MM = 80.1 g/mol),
how many grams of oxygen (MM = 32.0 g/mol) are
produced, assuming the decomposition goes to
completion?

It's a

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.

Idk the answer imthink snail cant mate they dont lol
