Answer:
The answer to your question is 2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂
Explanation:
Original chemical equation
NaCl + H₂O ⇒ NaOH + Cl₂ + H₂
Reactant Element Products
1 Na 1
1 Cl 2
2 H 3
1 O 1
This reactions is unbalanced
2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂
Reactant Element Products
2 Na 1
2 Cl 2
4 H 4
2 O 2
Now, the reaction is balanced
Given what we know, we can confirm that an example is a situation given that corroborates the information shown, while a non-example is one that does not fall in line with the information provided.
<h3>What are examples of the situations given?</h3>
- A number that is a multiple of 10 is 40, since 10 times 4 equals 40.
- In order to get a product of 10, we can multiply two and five.
- To result in a quotient of 10, we can divide one hundred by ten.
<h3>What are non-examples of the situations given?</h3>
- one non-example of a multiple of 10 would be to multiply three and seven.
- A non-example of a product of 10 is to multiply the number fifty by twenty-five.
- To result in a non-example for a quotient of 10, we can divide the number fifteen by three.
Therefore, given the definition of an example as a situation given that corroborates the information shown, while a non-example is one that does not fall in line with the information provided, we can confirm that the ones listed above are correct.

It’s chlorine not iodine because as we go down the group non metallic character decreases
The balanced chemical reaction is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we can see that 2 moles of HCl reacts for every 1 mole
of Mg(OH)2.
moles HCl left = 0.125 M * 0.150 L – (0.125 M * 0.040 L) *
2
moles HCl left = 0.00875 mol
So the concentration of H+ ion is:
[H+] = 0.00875 mol / (0.150 L + 0.040 L)
[H+] = 0.046 M
So the pH is:
pH = - log 0.046
<span>pH = 1.34</span>
