Answer:
4 g/cm³
Explanation:
Volume(V) = 60 cm³
mass (m) = 240 gm
density (d) = ?
We know density is defined as mass per unit volume so
d = m / v
= 240 / 60
= 4 g/cm³
Hope it will help

Hello!
In this case, given this is an acid-base neutralization and we are considering a diprotic acid, we can write the following mole-mole relationship:
It means that the moles of acid can be computed given the volume and concentration of NaOH:
It means that the approximate molar mass of the acid is:
Best regards!
Answer:
[A] + [B] decrease rapidly.
[CD] increases rapidly.
Explanation:
<em>A + B → CD,</em>
The reaction proceeds that A reacts with B and their concentration decreases to produce CD that its concentration increases with time.
At the beginning of the reaction; the concentration of A + B decreases rapidly and the concentration of CD increases rapidly.
