A stream containing $40$mole$\%$ decane $(C_{10}{H}_{22})$ and $60$mole$\%$ nonene $(C_9{H}_{18})$ mixture and a stream flow of $20$mole$\%C_{10}{H}_{22}-80\%C_9{H}_{18}$ are mixed and heated to $280C$ at constant pressure as shown in the Figure Q$3$ below. Using the specified assumptions and the enthalpies tabulated below, calculate the required heat for this process.
