Suppose that coal of density 1.5 g/cm^3 is pure carbon. (it is, in fact, much more complicated, but this is a reasonable first approximation.) the combustion of carbon is described by the equation:
c(s) + o2(g) > co2(g) ∆h° = −394 kj
what is the value of q (heat) when a lump of coal of size 5.6 cm x 5.1 cm x 4.6 cm is burned?
answer in units of kj.
