Scenario 4: Double replacement Double replacement reactions generally occur as ionic compounds are mixed.
Using research from the internet and your own knowledge of ionic compounds and
double replacement reactions, explain why these reactions occur between
ionically-bonded compounds.
Expectations:
A three-to five-sentence paragraph
References to your research (“According to..." or "In [source], the author says
that...")
DO NOT COPY A PARAGRAPH DIRECTLY FROM THE INTERNET. This
needs to be written in your own words.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
