Ammonia (nh3(g), hf = –46.19 kj/mol) reacts with hydrogen chloride (hcl(g), hf = –92.30 kj/mol) to form ammonium chloride (nh4cl(s), hf = –314.4 kj/mol) according to this equation: nh3(g) + hcl(g) nh4cl(s) what is hrxn for this reaction?

The for the given chemical reaction is -175.51 kJ/mol

Explanation: Enthalpy change of the reaction is defined as the amount of heat released or absorbed in a given chemical reaction.

Mathematically,

We are given a chemical reaction. The reaction follows:

Enthalpy change for the reaction of he given chemical reaction is given by:

Putting the values in above equation, we get

-175.9

Explanation:

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
