Question

When the gases dihydrogen sulfide and oxygen react, they form the gases sulfur dioxide and water vapor. (How would this be written in an equation?)

Answer 1

\[2H _{2}S _{(g)} + 3O _{2(g)} --> 2SO _{2(g)} + 2H _{2}O _{(g)} \]
or you could divide the whole thing by two, but you would have 3/2 O2

Answer 2

Convert 53.0 grams of C2H6 to moles of hydrogen
