Taking into account the reaction stoichiometry, 5.66 grams of H₂O are produced when 25 grams of water are formed.
In first place, the balanced reaction is:
Cu(OH)₂ → CuO + H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
The molar mass of the compounds is:
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
The following rule of three can be applied: If by stoichiometry of the reaction 79.55 grams of CuO are formed together with 18 grams of H₂O, 25 grams of CuO are formed together with how much mass of H₂O?
[tex]mass of H_{2} O=\frac{25 grams of CuOx18 grams of H_{2} O}{79.55 grams of CuO}[/tex]
mass of H₂O= 5.66 grams
Finally, 5.66 grams of H₂O are produced when 25 grams of water are formed.
