C) A student suggested five indicators that might be used in this titration: thymol blue
methyl orange
bromophenol blue bromocresol green phenolphthalein
How many of these indicators would be suitable? Use your Data Booklet.

A- 5
B- 4
C- 3
D- 2

Can someone please help me with all those 3 parts?

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

it is stable as it is in group 0 which have full outer shells of electrons
