Using the supplemental data, calculate the standard enthalpy change (in kj/mol) for each of the following reactions. (a) 2 na(s) + i2(g) → 2 nai(s) kj/mol (b) 2 koh(s) + co2(g) → k2co3(s) + h2o(g) kj/mol (c) b2o3(s) + 3 h2(g) → 2 b(s) + 3 h2o(l) kj/mol (d) ni(s) + cl2(g) → nicl2(s) kj/mol

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

58750.08068 is the answer i think

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
