The table below shows standard enthalpy changes of formation:
CO2(g) = -394
NH4NO3(s) = -366
H2O(g) = -242
What is the enthalpy change for the following reaction?
2NH4NO3(s) + C(s) + 2N2 (g) + 4H2O(g) + CO2(9)

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
