What is your question exactly?? lol sorry
Answer:
A model can represent something very large like the solar system, A model can represent something very small like a single cell, A model can represent something that cannot be seen or touched, A model can represent something very complex like the flow of energy in an ecosystem.
Explanation:
We know the equation of latent heat:
Q = mL
(Energy = mass * latent heat)
Therefore, this problem is a regular application of this:
Q = 25.4 * 61.7
Q = 1567,18
With the 3 digits:
Q = 1570 J
of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated. If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated.
