Answer:
100 %
Explanation:
<em>Relative humidity</em> (RH) is the amount of water vapour in the air compared to the maximum amount it can hold, expressed as a percentage.
RH is measured by a device that has wet- and dry-bulb thermometers.
If the air is unsaturated, water will evaporate from the wet bulb and cool it. The wet-bulb temperature will be less than that of the dry bulb.
If the wet-bulb temperature is the same as the dry-bulb temperature, it means that water cannot evaporate from the wet bulb.
The atmosphere already holds as much water as it possibly can, so the relative humidity is 100 %.
Answer:
The octet rule means that atoms need a total of 8 valence electrons to fill their valence shell. Hydrogen only needs two to fill its valence shell.
Explanation:
All atoms except for hydrogen can hold a total of 8 valence electrons in their outer energy levels (2 in the s level, 6 in the p level). Hydrogen only has two electrons total, so it does not require more than the s level and two electrons to have a full valence.
Friedrich Mohs devised a scale that tested mineral <span>hardness, </span>which means the resistance of a mineral to being scratched. This scale (from 1 to 10) is known as the Mohs Hardness Test. Objects are used as tools to perform the hardness test:
<span>fingernail (hardness = 2,5).
copper penny (hardness = 3)
glass plate or steel knife (hardness = 5,5)
<span>steel file (hardness = 6,5).
According to this scale </span></span><span>hardness of the mineral is between 5,5 and 6,5.</span>
The phase is Vaporization. ( But I am only about 50% sure)
