For a hydrogen atom, composed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10−18 joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom.
Answer:
There is a physical change as the water is evaporating, producing a gas.
Answer:
there would be different times because the sun and moon are in different places and one side would be sunny for a long time
Explanation:
Solids. Example: when you hit a drum, it vibrates, then the sound travels through the air, to your ears.
Considering that the water is at atmospheric pressure, its density at 21°C is still about 0.99 g/mL. The volume of the water is calculated by dividing the given mass by the density. That is,
Volume = mass / density
Substituting the known values to the equation,
volume = 23.2243 grams/ 0.99 g/mL
Simplifying,
volume = 23.46 mL
<em>Answer: 23.46 mL</em>
