3. Question three Hydrogen bonds are force that attracts molecules to each other in most liquids. Water can form up to . . bonds with neighboring molecules This is the reason why the melting and boiling points of water are much higher than those of other analogous compounds like hydrogen sulfide. They also explain its exceptionally high physical properties (i.e. specific heat capacity, heat of fusion, heat of vaporization, and thermal conductivity) . Answer the following: Common water treatment methods include aeration, sedimentation, ..and . . ..........g control Write about flocculation (Chemicals, The resulting of mixing with water). Softening is hardness removal method by using 1. ....agent , as it is sometimes known, and .are commonly used for water softening. 2.

(4d-202) A buffer solution is made by mixing H3PO4 and NaH2PO4 in water. How does this buffer system neutralize an addition of 5 mL of 0.45 M NaOH? Choose one of the options below. • The H3PO4, as a weak acid, will neutralize the added NaOH • The NaH2PO4, as a weak base, will neutralize the added NaOH • The H3PO4, as a weak base, will neutralize the added NaOH • The NaH2PO4, as a weak acid, will neutralize the added NaOH For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
