Answer:
It is the closest sir.
Have an amazing day and enjoy. P.S Good luck!
Explanation:
The correct answer is D
a polymer is a substance made up of large molecules with repeating sub units called monomers.
A is incorrect because its a ring structure which means it cannot form the long chain that is exhibited by polymers.
B is incorrect because the double bonds will cause saturation, hence no monomer can bond to another monomer to form the large molecule.
C is incorrect because the large molecule has repeating sub-units hence only specific types of molecules can be present, and it is usually carbon and hydrogen.
Answer:
Explanation:
First we find the Molecular weight of CaCl2
looking at the periodic table the MW of Ca is 40.078 and Cl is 35.453 and the ratio of ca to cl is 1:2 so we multiply cl by 2 which is 35.453*2=70.906
we add them together: 40.078 + 70.906 = 110.984 g/mol
now:
* 3.45 mol
the mol cancels out and we left with 3.45 * 110.984 grams = 382.89 grams
