what are the statements that you are able to choose from or do you just have to know?
(1,2 because c is already on the other side so you have to reverse it
Answer:
Explanation:
In this problem, we need to convert 
to miles per hour
We know that,
1 mile = 1.609 km
1 hour = 3600 seconds
Hence,
Answer:
1) phosphorus and chlorine
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
2) potassium and oxygen
type of bond = ionic
Due to high difference in electronegativities the form ionic bond.
3) fluorine and fluorine
type of bond = non polar covalent
They share their electrons and due to same electronegativities the form non polar covalent bond.
4) copper and aluminum
type of bond = metallic
copper and aluminum make metallic bond like other metals and mostly helpful in making alloys.
5) carbon and fluorine
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
6) carbon and hydrogen
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
7) aluminum and oxygen
type of bond = ionic
Due to high difference in electronegativities the form ionic bond.
8) silver and copper
type of bond = metallic
silver and copper make metallic bond like other metals and mostly helpful in making alloys.
The answer is the first sentence; "As the number of electrons in a molecule increases, the London dispersion force increases." :)
