At 1'30'' of the video the reaction is shown taking place. Write the chemical equation of this reaction. please answer short

Please help

I need a clear answer by hand, not by keyboard and solve very fast in 15 min | dybala

the video shows color changing everytime he adds a solution to it. solors just as plane and both colors seperated into the same big bowl.

Name: Due: Wed., 3/1/23 AP Chemistry 11. A student is instructed to determine the concentration of a solution of CoCl2₂ based on absorption of light (spectrometric/colorimetric method). The student is provided with a 0.10 M solution of CoCl₂ with which to prepare standard solutions with concentrations of 0.020 M, 0.040 M, 0.060 M and 0.080 M.

i) How many moles of hydrochloric acid were there in the volume of acid added in the titration? ii) How many moles of calcium hydroxide were there in the 25 cm sample of solution that the student used in the titration? iii) What was the concentration of the calcium hydroxide solution in mol/dm?

Before  Investigating the scene the technician must dilute the luminol solution to a concentration a 2.00 × 10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00L of the diluted spray?

Solving for a reactant in solution. Dimensional analysis.

I want the names of the programs in which I can draw the method with the instrument like in the picture
