For his 18th birthday in February Peter plants to turn a hut in the garden of his parents into a swimming pool with an artifical beach. In order to estimate the consts for heating the water and the house , peter obtains the data for the natural gas combustion and its price. Write down the chemical equations for the complete conbustion of the main components of natural gas, methane and ethane , given in table-1. Assume tht nitrogen is inert under the chosen conditions. Calculate the reaction enthalpy , the reaction entropy , and the Gibbs energy under standard conditons (1.013 xx 10^(5) Pa , 25.0^(@)C) for the combustion of methane and ethane according to the equations above assuming that all products are gaseous . The thermodynamic properties and the composition of natural gas can be found in table 1.

The XI^(th) class students of ALLEN designed a rocket. The rocket was launched from cycle stand of ALLEN straight up into the air. At t = 0 , the rocket is at y = 0 with V_(y) (t = 0) = 0 . The velocity of the rocket is given by: V_(y) = (24t - 3t^(2))m//s for 0 le t le t_(b) where t_(b) is the time at which fuel burns out. vertically upward direction is taken as positive. (g = 10m//s^(2)) The expression for the acceleration a_(y)(t) valid at all times in the interval 0 lt t lt t_(b) is
