<h2>Endothermic and Exothermic</h2>

Explanation:

An exothermic response discharges heat and endothermic absorbs to heat
The whole of the enthalpies of the reactants is more prominent than the product, the response will be exothermic
In the product that the items side has a bigger enthalpy, the reaction is endothermic
An exothermic method is one that emits heat. This heat is transferred to the environment
An endothermic reactions is one in which heat must be provided to the system from the environment

5000kg of ammonium nitrate per square kilometer of cornfield per year. how much nitric acid would be needed to make the fertiliz

Serggg [28]

$NH_3+HNO_3-> NH_4NO_3$

1 mole of nitric acid produce 1 mole of ammonium nitrate.

moles in 5000 kg of ammonium nitrate :

$n=\dfrac{5000\times 1000}{80}\\\\n=62500\ moles$ ( molecular mass of ammonium nitrate is 80 gm/mol )

So, number of moles of nitric acid required are also 62500 moles.

Mass of 62500 moles of nitric acid :

$mass = 62500\times 63 \\\\mass = 3937500\ gram\\\\mass = 393.75\ kg$

Hence, this is the required solution.
