The initial number of moles of the unknown acid (HA) is equal to the final amount of the number of moles of the known base (NaOH) because they fully consumed each other.
<h3>What is neutralization reaction?</h3>
Neutralization reactions are those reactions in which acids and bases reacts with each other for the formation of water and salt.
Acids reacts with base to form salt means all gets consumed by each other so the initial moles of an unknown acid is equal to the final moles of the known base.
And reaction between them is shown as:
HA + NaOH → NaA + H₂O
Hence acids and bases fully consumed each other that's why we can calculate the moles of unknown substance.

Answer:
False.
Explanation:
The chemical hazard label with colors indicates the specific class of hazard. Hazardous Materials Identification System is defined as the numerical hazard rating then incorporate the use of labels with colors.
Blue color: This sign conveys the health hazards of the material, means that long-term exposure to the material can cause the problems, for example kidney damage, and emphysema.
Red for color: This sign conveys the flammability hazards of the material.
Yellow for color: This sign conveys the instability hazards of the material.
