Answer:the strength of a bond depends on the amount of overlap between the atoms.
Explanation:the greater the overlap the greater the strength of the bond.
Answer:
The percent recovery from re crystallization for both compounds A and B is 69.745 and 81.44 % respectively.
Explanation:
Mass of compound A in a mixture = 119 mg
Mass of compound A after re-crystallization = 83 mg
Percent recovery from re-crystallization :

Percent recovery of compound A:

Mass of compound B in a mixture = 97 mg
Mass of compound B after re-crystallization = 79 mg
Percent recovery of compound B:

Answer:
physical
Explanation:
no chemical reaction is happening
This is true. Solid, Liquid, and Gas.
Hope that helps!!
Since this equation is balanced, we know that the law of conversation of mass id applied, and we could calculate easily.
Na= 2
NO3= 2
Ca= 1
