H 2 O = 18.02 u) To calculate mole fraction, we need the numbers of moles of water and of sugar. If we assume that exactly 1000 g of water were used, then we already know that the solution contains 2.00 moles of sugar. All we need is the number of moles in 1000 g of water,Acid and Base Ionization Constants. The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, the acid or base is termed strong; if relatively little ionization occurs, the acid or base is weak.As will be evident throughout the remainder of this chapter, there are many more …6.3 POGIL- MODEL 1 1-How many hydrogen atoms were int a molecule of water? -1 -2 -3 2-How many oxygen atoms will in a total of wat? 3- Get holds the hydrogen atoms to the oxygen iota? -hydrogen bond -covalent bond -ionic bond 4. Water has high boiling point and high thermal conductivity: Because of these properties water store and spreads heat and prevent from overheating. 5. Water has high heat of fusion: Water requires a loss of lot of heat to freeze. This prevents freezing and ice formation in the protoplasm even when exposed to very low temperature. 6.Terms in this set (43) What makes water so unique? Water is the only natural substance that is found in all three physical states at temperatures normally found on Earth. Why is water called a "universal solvent"? water dissolves more substances than any other liquid. What does it mean to have a pH of "7"? This means it is neither acidic or basic.13.
