Answer:
Van't Hoff factor for AlCl₃ = 3 (Approx)
Explanation:
Given:
Number of observed particular = 1.79 M
Number of theoretical particular = 0.56 M
Find:
Van't Hoff factor for AlCl₃
Computation:
Van't Hoff factor for AlCl₃ = Number of observed particular / Number of theoretical particular
Van't Hoff factor for AlCl₃ = 1.79 M / 0.56 M
Van't Hoff factor for AlCl₃ = 3.19
Van't Hoff factor for AlCl₃ = 3 (Approx)
Answer:
B - The atoms form a bond with a bond length of 75 pm
62 g of water are vaporized and the energy required is 2.4 kJ/g
So 62g x 2.4 kJ/g = 148.8 kJ or 148,800 Joules
Q = mCΔT
Q is energy in joules, m is mass of water, C is the specific heat, delta T is change in temp
148,800 = m(4.18)(41 - 19) = 1618g or 1.6 kg of water
Answer is: <span>1. products (NaCl(s)).
</span><span>This reaction is
exothermic, which means that heat is released. According to Le Chatelier's principle when the reaction
is exothermic heat is included as a
product </span>and when <span>the
temperature decreased, the heat of the system decreases, so the system consume shifting the equilibrium to the right, producing more sodium chloride.</span>
