Fe3+(aq) (yellow) + scn-(aq) (colorless) fescn2+(aq) (blood-red) chloride ions are colorless. potassium ions are also colorless. the above equilibrium can be created by mixing an iron (iii) chloride solution with a potassium thiocyanate solution. based on this information and the colors in the equilibrium above answer the first two questions. 1. what color would an fecl3 solution be? 2. what color would a kscn solution be? 3. what color do you get when you mix fecl3 and kscn as shown in the video for the control test tube?

Explanation:

The above two reactions xcan also be written in form of single chemcial equation:

1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.

2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.

3. On mixing, KSCN with we will get blood red color solution of .

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
