3D + A, B, → 3DB + 2A Molar Masses from periodic table: A=2.0 g/mol B= 6.1 g/mol D=4.3 g/mol How many grams of D do you need to react with 8.1 g A, B, ?​

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
