  • If the data in the problem are good, then you should not round a result that ends in 0.50. I would round down or up if the fraction were 0.10 or less and greater than 0.90. But if you get 0.50, double everything to change the X.50 into an integer. T…
  • Mass of chlorine (Cl) = mass of iron chloride - mass of iron = 7.55 - 2.60 = 4.95 g Cl. Convert g of Fe and g of Cl to moles by dividing by the atomic weights for each on the periodic table. 2.60 g Fe x (1 mole Fe / 55.85 g Fe) = 0.0466 moles …
  • First you have to write the reaction that they are talking about ... forming ethylene gas (C2H4) from its elements (C and H2) at 25 C. 2C(s) + 2H2(g) ==> C2H4(g) Let me label the equations that were given. (Equation 1) C2H4(g) + 3O2…
