Explanation: A hypothesis is a guess of what will or might happen before an experiment.
Air has a lower heat capacity which is the property of a material that describes how much heat energy is required to change the temperature of a substance by one degree Celsius <span />
Answer:
184 mL.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 62.8 mL
Initial concentration (C1) = 167 μM
Final concentration (C2) = 57.0 μM
Final volume (V2) =?
To obtain the final volume of the solution, we shall apply the dilution formula as follow:
C1V1 = C2V2
167 × 62.8 = 57 × V2
10487.6 = 57 × V2
Divide both side by 57
V2 = 10487.6 / 57
V2 = 183.99 ≈ 184 mL
Therefore, chemist must add distilled water to the solution until it reaches a volume of 184 mL.
The two jet streams that directly affect our weather in the continental US are the polar jet and the subtropical jet. They are responsible for transporting the weather systems that affect us. The polar front is the boundary between the cold North Pole air and the warm equatorial air.
