Answer:
Answer is shown on the paper :D
Explanation:
Remember to follow sig-figs.
An empirical formula presents the atoms of all the elements with the most simplified whole number ratios. In other words, divide each subscript by their greatest common factor.
The greatest common factor of 2 and 4 is 2.
2/2 = 1
4/2 = 2
So, the empirical formula for tetrachloroethene is CCl₂.
PH indicators detect the presence of H+ and OH-. They do this by reacting with H+ and OH-: they are themselves weak acids and bases. If an indicator is a weak acid and is coloured and its conjugate base has a different colour, deprotonation causes a colour change.
