Clasificación de los reactivos según su pureza

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.

Use the periodic table to determine how many grams of oxygen would be required to react completely with 859.0 g c2h2
