This question should have choices. These are the choices: A.) chemical properties of solute
the B.) type and polarity of the solvent C.)
the temperature D.) concentration of solute
A and B are related and is a huge factor in determining how well substances dissolve. C is again another key factor. Since the more we increase the temperature, for most substances, dissolution also increases. D would have to be the answer.
Planck's constant =
6.62607004 × 10-34 m2 kg / s
Explanation:
Step by Step explanation
The Planck constant, or Planck's constant, is a fundamental physical constant denoted h, and is of fundamental importance in quantum mechanics. A photon's energy is equal to its frequency multiplied by the Planck constant. Due to mass–energy equivalence, the Planck constant also relates mass to frequency. Wikipedia
The atmosphere is a envelope of gases surrounding another planet and the troposphere is the lowest part of the atmosphere
Answer:24 kilometers
Explanation:Density divided by time
The number of significant figures within a number are the amount digits that are required to specify a number to a certain degree of accuracy. In the number, 0.0645 g, the 6 is the most significant figure and 4 is the second most significant figure. Therefore, rounding to two significant figures yields 0.064g.
