Explanation:
Electrons are negatively charged. So it has a -3 charge.
- The density of the mineral fragment is
(20.47 g/cm3).
- Density can be regarded as<em> ratio of mass to the volume </em>of the object.
Density = (mass/ volume)
Given:
volume of mineral fragments= 2.57 cm3
mass = 52.6 g
density of the mineral fragment = (52.6/2.57)
= 20.47 g/cm3
- Therefore, density of the mineral fragment is (20.47 g/cm3)

According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.
<h3>What is Kinetic molecular theory ?</h3>
Kinetic molecular theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles which include atoms and molecules.
According to this theory, gas pressure arises due to particles colliding with each other and the walls of the container.
Because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases.
This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
Due to the sun's heat, the kinetic energy of particles in the balloon increases and it expands and continues to expand and comes to a stage when the balloon bursts.
Therefore,
According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.

To find the number of miles of NaOH, simply convert 49.80 ml into L, and then multiply it to the molar concentration of NaOH, so in this case the number of moles would be 0.04980 moles of NaOH. This would also equal the moles of H2O, as there is a 1:1 ratio between moles of base and moles of H2O.
I hope this makes a little sense? Review your acid and base chapters. Ive attached the autonionization of water and my work.
