In solid nacl, there is one kind of force holding the crystal together. in solid h2o, there are two kinds of forces within the crystal. identify the forces and explain.

i know that hydrogen bonds occur in between water molecules in ice, but what other intermolecular force exists?

Solid NaCl:

Solid H₂O:

NaCl is an ionic compound. It contains myriads of Na⁺ ions and Cl⁻. The two types of ions carry opposite charges. They attract each other via electrostatic forces. This type of electrostatic force is known as ionic bonds. Those bonds hold the ions in a gigantic ionic lattice.

H₂O is a covalent compound. Two H atoms are bonded to one O atom in each molecule. The O-H single bond is highly polar. Also, there are two lone pairs of electrons on the central O atom in each molecule. The O-H bond is so polar that the H atom carries a very strong partial positive charge. The H atom would be attracted to lone pairs on the O atom in neighboring H₂O molecules. Hydrogen bonds between the H₂O molecules hold them in place in their solid state.

There are two O-H single bonds in each H₂O molecule. H₂O molecules are V-shaped due to the presence of the two lone pairs on the central oxygen. Dipoles due to each O-H bonds do not line up within the molecule. As a result, H₂O molecules carry non-zero net dipole. They would attract each other by dipole-dipole interactions. That intermolecular force coexists with hydrogen bonds. It adds to the strength of the attractions between H₂O molecules.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
