This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
Evaporation happens<span> when atoms or </span>molecules<span> escape from the liquid and turn into a vapor. Not all of the </span>molecules in a liquid have the same energy. <span>Sometimes a </span>liquid<span> can be sitting in one place (maybe a puddle) and its molecules will become a </span>gas<span>. That's the process called </span>evaporation<span>. It can happen when liquids are cold or when they are warm. It happens more often with warmer liquids. You probably remember that when matter has a higher temperature, the molecules have a higher </span>energy<span>. When the energy in specific molecules reaches a certain level, they can have a </span>phase change<span>. Evaporation is all about the energy in individual molecules, not about the average energy of a system. The average energy can be low and the evaporation still continues. </span>
Answer: a. 
Explanation:
When silver nitrate 
combines with potassium chromate 
,they undergo double displacement reaction in which exchange of ions take place.
The products formed are silver chromate 
which is insoluble in water and thus formed as precipitate and potassium nitrate 
is soluble in water.
Answer: C. Harmful, because it will have a harder time sneaking up on its prey
Explanation: White skin on an alligator would be detrimental because it would not be able to blend in to its surroundings as well, as the white skin would stand out from the greens and browns of the swamps in which alligators normally inhabit. Most alligators also live in warmer climates, so there would not be much opportunity to try and blend into any sort of snow.
