How does the law of conservation of mass apply to this reaction: c2h4+o2--> 2h2o+2co2? the equation needs to be balanced. there are fewer oxygen atoms in the equation than hydrogen or carbon. only the oxygen needs to be balanced. there are equal numbers of hydrogen and carbon. the law of conservation of mass has already been applied. there is an equal number of each element on both sides of the equation. each element needs to be balanced

The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

took the quiz

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
