Short answer question 1. The figure represents a water molecule. Draw a second water molecule to show how bonds can form between water molecules, including the name of the bond. [2 marks] 2. Water has important
A water molecule consists of one oxygen atom and two hydrogen atoms. Oxygen has a very high electronegativity, meaning it has a very high affinity for electrons. The oxygen in water molecules pulls the electrons from the hydrogen atoms closer to it, creating two poles in the molecule, where ...

This results in polar properties of the water molecule (it has a dipole moment of 1.85 debye). Many of the special features of the water molecule are due to this polarity. Of particular importance is the distinctive tendency of the water molecules to form hydrogen bonds with one another or ...
Water molecules are very cohesive because of the molecule's polarity. This is why you can fill a glass of water just barely above the rim without it spilling.Solid State (Ice)All substances, including water, become less dense when they are heated and more dense when they are cooled. So ...
Water Molecule | Properties, Structure & Polarity from Chapter 5 / Lesson 22 56K Learn about water molecules and their polarity. Understand water molecule structure, whether water is polar or nonpolar, and what makes water a polar molecul...
Answer to: Explain why water is a polar molecule. What do the polarity and shape of water molecules have to do with their ability to form hydrogen...
Organic condensation reactions eliminate a water molecule: CH3COOH + C2H5OH → CH3COOC2H5 + H2O Many hydroxides dehydrate at high temperatures forming oxides and water: Ca(OH)2 → CaO + H2O Water can be purified by distillation, ion exchange, filtration, carbon adsorption, and chlorination. ...
1) polarity water molecule 极性水分子 2) molecule polarity 分子极性 1. The main purpose of grafting of maleic anhydride onto polyolefins is to increase themolecule polarity. PPB-MAH的缔合力参数可以用来量化表示其分子极性,椭圆方程可以用作溶剂的可溶性的预测。
