Answer:
The correct answer is 2.33g of 
, A
Explanation:
We can use basic stoich to get this question.
To start, lets convert our grams to moles in order to use our equation. 5.38g of 
moles.
We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of 
to moles of . This gets us 0.129335 moles of .
Now lets convert to grams of by multiplying by the molar mass of . 
of
Answer:
Metallic bonds
Explanation:
Metallic bonds joins atoms of metals and atoms of alloys together. The copper used in making pennies is a metallic substance so it contains metallic bonds.
- The formation of this bond type is predicated on the large atomic radius, low ionization energy and large number of electrons in the valence shell.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud.
- The electron cloud is jointly formed by all the atoms by losing their outermost shell electrons.
This way the bond in pennies are metallic in nature.
