What kind of bond would form between NH_4 and Cl^- to make the salt ammonium chloride (NH_4Cl)? Iconic. Polar covalent. Hydrogen. Nonpolar covalent. A or C, depending on conditions. When two atoms are equally electronegative, they will interact to form a hydrogen bond. nonpolar covalent bond. pair of ions. ionic bond. polar covalent bond. A(n) occurs between nonpolar molecules. ionic attraction van der force hydrogen bond nonpolar covalent bond Which of the following statements about the density of water is accurate? dense than water vapor. Liquid water is denser than ice, which is more water behaves like other substances in terms of density. At all temperatures, water vapor. liquid water, which is water vapor is denser than ice, which is more dense than liquid water. Solution Answer: Answer: 6). a). Ionic NH4Cl, or Ammonium Chloride, is a salt, which means it has an ionic bond. 7). d). nonpolar covalent bond Nonpolar covalent bonds are a type of chemicalbond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. 8). c). van der Waals force If the molecule is nonpolar, then no dipole-dipole interactions or hydrogen bonding can occur and the only possible intermolecular force is the weak van der Waals force 9). a). Liquid water is more dense than ice, which is more dense than water vapor When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water.Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. In the gas/vapor phase, molecules have very little interaction with each other and they are at large distance, whereas in liquid and solid, molecules are in continuous contact with each other. It is therefore clear that there are more molecules per liter in ice than in water vapor, and therefore the density is larger..
