answer: for the given reaction is -851.4 kj/mol.
enthalpy of the reaction is equal to the total sum of the standard enthalpies of the formation of products minus the total sum of the standard enthalpies of formation of reactants. it is represented by
for the given reaction:
the standard enthalpy of the elements present in their standard state is always zero.
for the reaction is calculated by:
we are given:
putting values in above equation, we get:
hence, for the given reaction is -851.4 kj/mol.
the answer is the total amount of energy stays the same.
- according to the conservation law of mechanical energy, for a closed system that entails the presence of just conservative forces ( independant on the pathway between two points), the total mechanical energy of the system (which is the sum of potential and kinetic energies) remains constant (stays the same).
- clearly, the sum at any of the 4 points = 50 j..
a) the code has punctuatio...
