Answer:
2) It can be performed in natural settings
Answer:
21 mL of NaOH is required.
Explanation:
Balanced reaction: 
Number of moles of HBr in 11.0 mL of 0.30 M HBr solution
= 
moles = 0.0033 moles
Let's say V mL of 0.16 M NaOH solution is required to reach equivalence point.
So, number of moles of NaOH in V mL of 0.16 M NaOH solution
= 
moles = 0.00016V moles
According to balanced equation-
1 mol of HBr is neutralized by 1 mol of NaOH
So, 0.0033 moles of HBr are neutralized by 0.0033 moles of NaOH
Hence, 
So, 21 mL of NaOH is required.
Answer:
8:10
Explanation:
The coefficients of a balanced chemical equation give us the mole ratios. The coefficient of carbon dioxide here is 8 and water is 10.
Answer:
Earthquake
Explanation:
Notice how it is starting to shift allowing the earthquake to form.
In the reaction, Na⁺ + 6H₂O ⇆ Na (H₂O)⁺₆, Na⁺ is a Lewis acid and H₂O is a Lewis base.
<h3>
What is a Lewis acid-base reaction?</h3>
- According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
- Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
- Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
- Here Na⁺ that is electron deficient accepts electrons from the electron donor, H₂O
- From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.
