The density of a substance is its mass per unit volume, given by the mass divided by the volume. Density depends on the substance of concern and doesn't matter whether one has a little amount of it or a whole full of it. Therefore, the density of the two smaller pieces is now the same as the original density.
Answer:
2H₂O₂ → 2H₂O + O₂
Explanation:
H₂O₂ → H₂O + O₂
The above equation can be balance as illustrated below:
H₂O₂ → H₂O + O₂
There are 2 atoms of O on the left side and a total of 3 atoms on the right side. It can be balance by putting 2 in front of H₂O₂ and 2 in front of H₂O as shown below:
2H₂O₂ → 2H₂O + O₂
Now, the equation is balanced.

Answer:
The titrant is a strong acid while the analyte is a strong base
Explanation:
A titration curve is a graphical representation of the pH of a solution during a titration. The figure in the question shows a particular example of a strong acid-strong base titration curve. This is a titration in which the acid is added to the base thus the pH progresses from low to high.
Hence, the titrant is the strong acid delivered from the burette while the analyte is the base as shown by the titration curve in which acid is delivered to the base.
