Suppose that coal of density 15 gcm3 is pure carbon it is

Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable ?rst 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 6.3 cm × 5.8 cm × 5.3 cm is burned?
