Title: Calculating Moles in a Reaction Post by: stereohearts on Jun 30, 2019 In the chemical reaction of iron and sulfur:
2Fe(s) + 3S(s) → Fe2S3(s) (a) How many moles of sulfur are needed to react with 1.42 moles of iron? (b) Calculate the number of moles of iron needed to react with 2.75 moles of sulfur. - - - When acetylene, C2H2, burns in oxygen, high temperatures are produced that are used for welding metals. 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g) How many grams of CO2 are produced when 54.6 g of C2H2 is burned Title: Re: Calculating Moles in a Reaction Post by: bio_man on Jul 2, 2019 https://www.youtube.com/watch?v=XoNeBNROBcI
