<h3>... :-!...................nose...........</h3>
Explanation:
Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified.
Are produced 72 grams of water in this reaction.
<h3>Mole calculation</h3>
To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:2, so we can perform the following expression:



So, if there are 2 mols of Ca(OH)2:
Ca(OH)2 | H2O


Finally, just find the number of grams of water using your molar mass:


So, 72 grams are produced of water in this reaction.
