The ml is also called as the magnetic quantum number. The value
of ml can range from –l to +l including zero. Hence all of the possible values for ml given
that l = 2 are:
<span>-2, -1, 0, + 1, + 2</span>
<h3>1. <u>Answer</u>;</h3>
= 5.4×10-6 g AgBr
<h3><u>Explanation</u>;</h3>
AgBr(s) → Ag+(aq) + Br-(aq) Ksp = 3.3×10^-13
[Ag+][Br-] = Ksp = 3.3×10^-13 = X²
X = 5.7×10^-7 M = [Ag+] = mol/L AgBr that dissolve
1 mole of AgBr = 187.8 g
Therefore;
= 0.05 L × (5.7 × 10^-7 mol/L) × (187.8 g /mol)
= 5.4×10-6 g AgBr
<h3>2. <u>Answer and explanation;</u></h3>
The two factors that accounts for increased rate of chemical reaction when temperature is increased are:
- <u>Energy factor</u>; enough energy in the collision for the formation of an activated complex, where bonds are breaking and new ones forming. When temperature is increased, a greater number of molecular collisions possess enough energy to activate the reaction.
- <u>Frequency of collisions increases;</u> an increase in temperature makes particles move faster and collide more frequently, increasing the possibility of a reaction be-tween them.
More important factor; Energy factor is more important.
