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.
Answer:
yes
Explanation:
it wont dissolve because when water is cold its molecules dont separate
The answer would be using proportions 151/x=166/0.532, then you solve for x. The answer would be <span>0.483927711, but then you have to round it and get approximately 0.484 L. Hope this helps! Happy Studying!</span>
Is it multiple choice? If not, the main reason would be the ability to escape from prey, or move to a different climate based on the individual needs.
