For the reaction C+2H 2 —->CH 4 calculate the percent yield if 98 g of methane is produced when 100. g of carbon reacts with an excess of hydrogen?

The percent yield : 73.5%

Given

Reaction

C+2H₂⇒CH₄

Required

The percent yield

Solution

mol of Carbon(as a limiting reactant) :

mol CH₄ based on C, and from equation mol ratio C : CH₄, so mol CH₄ = 8.3

Mass of Methane(theoretical yield) :

passing a magnet thought the

mixture , because iron gets attracted to magnet .

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being
