Answer:
A-A and B-B attractive forces contains more energy than AB attractive forces
Explanation:
AA and BB are separated as solutes and solvents in themselves which is an endothermic reaction ΔH<0 while they are free to react to form the product AB that contains lesser amount of energy than the reactants AA and BB of which the excess energy is observed as increased temperature of the solution
ΔH<0 : Exothermic Reaction (negative), because the the products less energetic than reactants.
Dispersing the molecular bonds of the solute AA and the solvent BB solutions by themselves are generally endothermic reactions in as their cohesive forces are broken down to allow them mix, while allowing the free reaction of the molecules is an exothermic reaction as they form the solution component AB which is less energetic accompanied by excess energy as that is observed in heat of the reaction
This answer would be a blood vessels
S + O2 --> So2. P = 101kPa = 1atm. R = 0.082 atm - L - (mol-K)^-1. Applying ideal gas equation PV = nRT. n = 1x4.5/0.082x573 = 0.096mole. According to stoichiometry, moles of S = moles of SO2 = 0.096mol. Mass of S = moles of So2 x molar Wt = 0.095x32 = 3.04moles. Hope it helps
if your n is 6 then the 2nd number is 5.
the order is this
n, 0 --> n-1, -L <-> L, and then either -1/2 or +1/2. i know its really confusing i hate chem myself, but its kinda ironic cuz this was the only thing i understood haha
All you have to do is a simple division "parts over the whole"
12.3 grams H/ 110 grams compound x 100= 11.2%
