The conversion for km to inches is:
1km=39370.1in
Now we can solve for 56 km..
56km=39370.1*56
56km=<span> 2204725.6in
Answer=2,204,725.6in</span>
Answer:
Sunscreen is like a shield, you would want a better shield to protect you than a weak one so companies try to make their sunscreen better than the rest.
Answer:
and 
. The missing ion would be 
.
Explanation:
In a double replacement reaction, two ionic compounds exchange their ions to produce two different ionic compounds.
In this question, the two ionic compounds are:
, and
.
In particular,
- is made up of
ions and 
ions, while - is made up of
ions and ions.
In a binary ionic compound, cations (positive ions) can only bond to anions (negative ions.)
- is a cation. In , was bounded anions. During the reaction, it bonds with anions to produce .
- is also a cation. In , was bounded to ions. During the reaction, it bonds with anions to produce .
Hence, the two products will be and .
Note that charges on the ions must balance. For example, a ion carries twice as much charge as an ion. As a result, each ion would bond with twice as many ions as would in .
Answer:
Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.
