The reaction between FeS and O2 is shown below. 4FeS + 7O2 = 2Fe2O3+ 4SO2 how many moles of sO2 gas will be produced from 3.1 moles of oxygen?

i believe it is 40–40–20%

explanation:

thats a little if u want the answer just look it up on google thats what i do haha : )

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

answer: they produce more slow than unicellular organisms.
