How many moles of nitrogen gas is needed to react with 84.8 liters of hydrogen gas to produce ammonia gas? *giving brainliest please show work*

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the product of the pressure and volume is also constant

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
