Answer:
The concentration of NaOH solution is 3,65M
Explanation:
The neutralization of NaOH with HCl is:
NaOH + HCl → NaCl + H₂O
You are titrating 12,67 mL HCl 2,74M with your NaOH solution, the moles of HCl in the beaker are:
12,67 mL ≡ 0,01267L×
= <em>0,0347 moles HCl </em>≡ 0,0347 moles NaOH
The volume that you require for total neutralization of 12,67 mL HCl 2,74M is:
13,65 mL - 4,50 mL = <em>9,50 mL </em>≡ 0,0095L
Thus, the concentration of NaOH solution is:
= <em>3,65M</em>

Answer:
Sodium chloride (NaCl)
Explanation:
According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.
Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.
For example: <u>Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)</u>
A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).
<em>The chemical equation for this Neutralization reaction:</em>
HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)
<u />
<u>Therefore, </u><u>sodium chloride (NaCl) is the salt formed</u><u> during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).</u>

The energy source of tsunami waves is much greater
Explanation:
The major difference between a tsunami waves and ripple waves is that the energy source of tsunami waves is much greater compared to ripple waves.
Tsunami waves carry more energy compared to just a disturbance resulting from a ripple caused by dropping of a stone.
- A tsunami is a large water wave caused by the displacement of water usually by an earthquake.
- An earthquake is a releases elastic waves suddenly within the earth crust.
- Water bodies at the epicenter are disturbed sending huge volume of energetic water loads to the land.
- A ripple is just a product of a stone dropped inside the water.
Tsunamis are more energetic compared to ripples in water.
