Answer:
a colloid and a solution
Explanation:
When solute particles completely dissolve in a solvent, a true solution is formed. The solute particles in this case are so little that they can not be seen with naked eyes. A true solution does not scatter rays of light.
In a false solution, the solute particles are larger than the solute particles in true solutions but are not large enough to be seen with naked eyes. False solutions scatter rays of light. False solutions are also called colloids.
The major difference between a solution and a colloid is that colloids scatter light rays (Tyndall effect) while a true solution does not scatter light rays.

The neutron is electrically neutral.
Answer: 0.85075J/g.K
Explanation:
Mass of the material = 100g
Energy (Q) = 5104.5J
T1 = 20°C = 293K
T2 = 80°C = 353K
Formula for heat energy (Q) = mc ∇T
Q = mc∇T
∇T = T2 - T1
∇T = 353K - 293K = 60K
Q = mc∇T
C = Q / m∇T
C = (5104.5) / (100 * 60)
C = 0.85075 J/gK
The specific heat capacity of the material is 0.85075J/gK.
Answer:
K(70°C) = 2213.376 s-1
Explanation:
balanced reaction:
- NO(g) + O3(g) → NO2(g) + O2(g)
∴ Ea = 63 KJ/mol
∴ A = 8.7 E12 s-1
∴ T = 70°C ≅ 343 K
Arrhenius eq:
∴ R = 8.314 E-3 KJ/K.mol
⇒ K(70°C) = (8.7 E12 s-1)e∧[-(63)/(8.314 E-3)(343)]
⇒ K(70°C) = (8.7 E12 s-1)*(2.5444 E-10)
⇒ K(70°C) = 2213.376 s-1
