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.

Answer:
A pH of 7 is neutral.A pH of less than 7 is acidic.
Explanation:
Answer:
0.01 faraday
Explanation:
We'll begin by writing the balanced equation. This is illustrated below:
CaCl₂ (aq) —> Ca²⁺ (aq) + 2Cl¯ (aq)
Ca²⁺ (aq) + 2e —> Ca
Molar mass of Ca = 40 g/mol
Mass of Ca from the balanced equation = 1 × 40 = 40 g
1 mole of electron (e) = 1 faraday
2 moles of electrons (e) = 2 × 1 faraday
2 moles of electrons (e) = 2 faraday
From the balanced equation above,
40 g of Ca was deposited by 2 faraday.
Therefore, 0.2 g of Ca will be deposited by = (0.2 × 2)/40 = 0.01 faraday.
Thus, 0.01 faraday is needed for the reaction.
