In a calorimetry lab, sodium oxide is combined with water. Compute the heat released in the formation of 1.99 grams of sodium hydroxide. Na2O +
H2O -> 2NaOH + 215. 76 kJ

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
