A compound is 42.9% carbon by mass, and contains only carbon and oxygen. The empirical formula for this compound is C(_) O (_)

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

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.
