First you need to know what is a semantic memory
Semantic memory, is a more structured record of facts, meanings, concepts and knowledge about the external world that we have acquired.
So ,The element which is a semantic memory is learning from her father that salt water is more dense than fresh water.
Hope this helped :)
If I am reading this question correctly, then the answer is "no, every collision between reacting particles lead to a product". You have to address the energy component of the particles. If there isn't enough energy to allow the reaction to occur, then the particles will elastically bounce off one another and no reaction will occur. If there is enough energy, then the reaction will occur.

Answer:
a. 0.80 m³/kg
b. 0.67 m³/kg
Explanation:
a.
Step 1: Given data
Volume of the container (V): 20 m³
Mass of methane (m): 25 kg
Step 2: Calculate the specific volume (v) of methane
Specific volume is defined as the number of cubic meters occupied by one kilogram of matter.
v = V/m
v = 20 m³/25 kg = 0.80 m³/kg
b.
Step 1: Calculate the mass of the mixture
m = m(methane) + m(ethane)
m = 25 kg + 5 kg = 30 kg
Step 2: Calculate the specific volume (v) of the mixture
v = V/m
v = 20 m³/30 kg = 0.67 m³/kg
