The change in the internal energy of the chemical system (ΔE) can be calculated using the equation:
ΔE = Heat (Q) + Work (W)
Given that 454 Joules of heat are generated (Q = 454 J) and 790 Joules of work are done on the system (W = 790 J), we can substitute these values into the equation:
ΔE = 454 J + 790 J
ΔE = 1244 J
