Sulfur react with fluorine according to the equation: S (s) + F2 (g)  SF6 (g)

1. Balance the equation

2. Calculate the quantity of matter of SF6 obtained when 5g of sulfur react with fluorine

3. Deduce the mass of the obtained product

M(S) = 32 g. mol-1

; M(F)= 19 g. mol-1​

Before it was launched, a helium-filled balloon had a pressure of 201 kpa at a temperature of 27°c. at an altitude of 15,000 m, the pressure had decreased to 2.5 kpa and the temperature had dropped to -14 °c. the volume of the balloon increased to 59.3 m3. what is the original volume of the balloon? 13 m3 0.85 m3 0.077 m3 1.17 m3
