Why is the bond angle of water greater than hydrogen sulphide? How is a covalent bond different from an ionic bond? Why is bond breaking endothermic? How can you tell if a chemical bond is polar or not? How is a hydrogen bond different from a covalent bond? Why is amm...
Water is a unique substance. It expands when it freezes, it takes a lot of energy to raise its temperature, and it dissolves many things. These characteristics all stem from the geometric shape of water. Answer and Explanation: Water molecules are attracted to each other because opposite sides...
Calculate the ionic character (IC%) of the interatomic bond for CaF 2 ? Consider a system fed with 4 kmol of N2 and 1 kmol of H2 that reacts to form NH3. Determine an expression for Kp as a function of the reaction co...

London Force: Instantaneous dipole creation that affects the electronegativity between atoms. It is considered a weak intermolecular attractive force. Answer and Explanation:1 The oxygen molecule, O2, contains two identical atoms, and as a result, there is no difference in electronegativity across the...
Why is water cohesive? Why are some alcohols soluble in water? Why is polarity important? Why can water dissolve many substances? Why are the molecules of hydrocarbons nonpolar? Why is solubility important to life? Why is NH3 soluble in water? Why are coordination compounds important? Why is ...
Explain why gasoline does not dissolve in water. Hydrophobic: Hydrophobic translates into 'water fearing', and in the chemistry world, it means just that; a hydrophobic molecule will not mix with water. Hydrophobic molecules are often non-polar, which means the molecule does not have a charge ...
Why is NH3 soluble in water? Why is saturated steam a common heating medium? Give two reasons why water formation (condensation) might not be observed in bunsen burner experiments? Why is sodium bicarbonate added to water? Why is copper used for most electrical wiring? Why are some substances...
Why is ammonia (NH3) a covalent bond? Describe how hydrogen bonding accounts for the properties of water? How does a polar covalent bond differ from a nonpolar covalent bond? What attracts the atoms in an ionic bond? Which bond is the strongest when placed in order from greatest to le...
