Aconcept map for four types of intermolecular forces and a certain type of bond is shown.

which of the following correctly identifies the intermolecular force represented by a and compares its strength relative to the intermolecular force represented by b?

a represents london dispersion forces, which are weaker than the force represented by b.
a represents hydrogen bonding, which is weaker than the force represented by b.
a represents london dispersion forces, which are stronger than the force represented by b.
a represents hydrogen bonding, which is stronger than the force represented by b.

A represents London dispersion forces, which are weaker than the force represented by B.

Explanation:

London Dispersion Forces : Intermolecular forces exist  between non-polar molecules.  They are very weak forces.  Thought to be arise from the  motion of electrons.

H-bonding: It is a special type of dipole-dipole interaction  between the H-atom in a polar bond such as N-H,  O-H, F-H and an electronegative atom such as  nitrogen, oxygen and fluorine.

It is clear that H-bonding is stronger than London-dispersion.

So, the right choice is:

A represents London dispersion forces, which are weaker than the force represented by B.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
