attraction:
a. polar molecule and polar molecule
b. nonpolar molecule and nonpolar molecule
C. polar molecule and ion
d. ion and ion
Answers
Arranging the pairs from strongest to weakest attraction :
Nonpolar molecule and Nonpolar molecule ( B )Polar molecule and Polar molecule ( A )Polar molecule and Ion ( C )Ion and Ion ( D )Covalent bonds are the strongest bonds because it involves the sharing of electrons between two binding atoms therefore the atoms are not dissociated easily. Also covalent bonds are divided into ;
Polar covalent bonds ; The shared electrons from each atom involved are unequal therefore it is easier to dissociate polar molecule bonds ( i.e. weaker bond ). Non Polar covalent bonds ; The shared electrons from each atoms are equally therefore it is harder to dissociate nonpolar molecule bonds ( i.e. stronger bond when compared to polar bonds ).While Ionic bonds involves the transfer of electrons from a donor atom to another atom and such bonds are easily broken and it is a weaker bond when compared to Polar and Nonpolar bonds. therefore polar molecule and ion bond pair is stronger than ion and ion pair.
Hence we can conclude that ranking the pairs from strongest to weakest attraction is as follows; Nonpolar molecule and Nonpolar molecule, Polar molecule and Polar molecule, Polar molecule and Ion, Ion and Ion.

Answer:
1. D 2.. A 3. C 4. B
Explanation:
just took the quiz
We can classify each rock as intrusive or extrusive and basaltic or granitic as follows; Rock A - Extrusive, Basaltic, Rock B - Intrusive, Granitic, Rock C - Extrusive, Basaltic, and Rock D - Extrusive, Basaltic.
Rock A - Extrusive, Basaltic
Rock A is described as having dark-colored large grains, which indicates a fine-grained texture, typical of extrusive rocks. The presence of dark-colored large grains suggests a basaltic composition.
Rock B - Intrusive, Granitic
Rock B is described as having large crystals and a high percentage of silica, which suggests a coarse-grained texture, typical of intrusive rocks. The high silica content and large crystals indicate a granitic composition.
Rock C - Extrusive, Basaltic
Rock C is described as having a fine-grained texture and being light-colored, which are characteristic features of extrusive rocks. The fine-grained texture suggests a rapid cooling, typical of extrusive rocks, and the light color is indicative of a basaltic composition.
Rock D - Extrusive, Basaltic
Rock D is described as being from the Hawaiian volcano area and having no visible crystals. This indicates a glassy texture, typical of rapidly cooled extrusive rocks. The origin from a volcanic area and glassy texture suggest a basaltic composition.
