5. A compound containing sulfur, nitrogen, and hydrogen has a composition of 86.6% sulfur, 12.6% nitrogen, and 0.91% hydrogen by mass. A solution prepared by dissolving 3.130 g of this compound in 25.00 g of bromoform, CHBr3, produces a solution that freezes at –0.31°C. What is the molecular formula of the compound? (Kf for bromoform is 14.4°C/m, and pure bromoform has a freezing point of 7.8°C.)

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

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.
