1. The reaction Fecl3 + H20 (cold water)
i. Observation: what is the color of product formed and is it a solution, precipitate or a gelatinous precipitate.
ii. Inference: e.g is any ion present like fe3+, fe2+ etc
2. divide the result of the solution formed above into 2 portions (in 2 test tubes)
3. Take portion ONE and react it with dilute hcl
i. Observation : is there any color change or precipitate formed
ii. inference: What is the inference for the reaction i.e is any ion like fe3+ present or confirmed

1. Is the product formed from the reaction between iron iii chloride and water a solution or a precipitate.

the present of hydrogen bond in most molecules is responsible for

What do you understand by centre of Inversion?

I do have a question about the concentration factor that affect the rate of reaction? Concentration. this is the measure of how crowded the particles are in a solution and the frequencies of collision. the gaseous equivalent of this is ----------?
what is the answer for that blank at the end

Why is double bond stronger than single bond?
Why does double bond require more space than single bond?
Why is double bond-double bond repulsion more than double bond-single bond and single bond-single bond repulsions?
Are there any other important comparisons between the two?

c. result of reaction 2 above then heated +concentrated HNO3 and heat
d. result of reaction 3 above + NH4CL AND NH4OH
2. solution of Fecl3+H20+H202+ HEAT

WHAT IS THE OBSERVATION AND INFERENCE OF THE REACTION BETWEEN WATER AND FECL3

Among the Group 4 elements moving from carbon to silicon the covalent radius increases sharply afterwards the increase is gradual, this is attributed to __________.

I have not understood this line from J D lee.- 'The ionisation energy for an atom is always positive and for an ion may be negative. (Why negative when heat is supplied?) If IE can be negative, please give me an example of the same. I am quite confused.
