Mililiters
% (V/V) = [V of solute / V solution ] *100
20.0 / 100 = V of solute / V solution = V of solute = 0.2 * V of solution
V of solution = 240.0 mL
=> V of solute = 0.2*240.0 mL = 48 mL
Answer: 48 mL
Answer:
its true i just looked on quizlet
Explanation:
B.Several chemical changes occurred. I conclude that a chemical reaction took place
Explanation:
From the observation, Jason can conclude that several chemical changes occurred and a chemical reaction has taken place. In a chemical change, often times, new products are usually formed.
- A chemical change is one in which new kind of matter is formed.
- Chemical changes are products of chemical reactions.
- The rearrangement of atoms in reacting species and the formation of bonds leads to chemical reactions.
- Chemical changes are irreversible, no change in mass(mass is conserved) and they require considerable amount of energy.

Explanation:
As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other. The intermolecluar forces holding the molecules together become weaker
The relationship between Fahrenheit and Celsius is:
°F = 1.8*°C + 32
If we differentiate the given expression to find the relationship between a unit change of °F and °C, we get:
Δ°F = 1.8*Δ°C
This means that a change in 1 degree Fahrenheit is equivalent to a change of 1.8 degrees Celsius. Moreover, a one degree change in Fahrenheit is the same as a one-degree change on the Rankine scale, so, ranking the scales in order from higher change to lower change:
1) Fahrenheit = Rankine
2) Celsius = Kelvin
