Fungus: Important because it breaks up several dead leaves, particles, etc, and puts nutrients back in the ground.
Carnivores: eat dead animals, no stinky rotten meat around.
Te answer is interval between any two elements in the activity series increases. <span>The tendency for a replacement reaction to occur increases as the i</span>nterval between any two elements in the activity series increases.
Answer:
The freezing point of the solution is 78.71 °C
Explanation:
Step 1: Data given
Freezing point for the pure solvent is 79.4 °C.
Molality = 0.1 molal
Freezing point depression = 6.9 °C/m
Step 2: Calculate freezing point of the solution
ΔT = i*Kb*m
⇒ with i = the van't Hoff factor: naphthalene = a non-electrolyte, which means that the van't Hoff factor for this solution will be 1
⇒ with Kb = the freezing point depression constant = 6.9 °C/m
⇒ m = the molality = 0.1 molal
ΔT = 1 * 6.9 * 0.1
ΔT = 0.69
Freezing point of the solution = 79.4 °C - 0.69 = 78.71 °C
The freezing point of the solution is 78.71 °C
