When solid KBr is dissolved in water, the solution gets colder. Is this an exothermic process? Explain. Using Le Chatelier's principle, explain why liquid water spontaneously converts to solid ice when the temperature drops below 0 degrees Celsius (at 1 atm). ...
Why does ice float in water even though ice is just melted water? Explain why the water boils when it was cooled with ice. Why is ice less dense than liquid water? Explain how you would prepare a 1.135 m solution of KBr in water. How can you explain the melting of ice is not a ...
(HDPE) is investigated. The impregnation of paraffin Pickering emulsion could significantly improve the WF dispersion in HDPE matrix, resulting in increased melt flow index (MFI). It increased from 1.3 g/10 min (control) to 2.1 g/10 min (Pickering treatment) due to the lubrication of paraffin...

Give the ion when the strong electrolyte dissolves in water. NaSCN How does an electrolyte differ from a nonelectrolyte? (a) Electrolytes are more reactive than nonelectrolytes. (b) Electrolytes are smaller than nonelectrolytes. (c) Electrolytes dissolve ...
Why do we use prefixes only in covalent compounds? With reference to covalent and ionic bonds. why does protein not dissolve in water as salt does? Which bond is stronger, ionic or covalent? Why is Technetium-99m (the element, Technetium) a good radionuclide to ...
Explain how you would prepare a 1.135 m solution of KBr in water. Explain what distillation is and describe the phase changes that occur during the process. Explain how a mixture of phenol and cyclopentanol might be separated using differences in their solubility properties. What is ...
What mass of AgNO3 would you dissolve in water in order to get 1.00 g of silver? What will happen when SO_4^{2-} is added to AgNO_3 + HNO_3. What will happen when the element is added to the aqueous solution: Ca. What will happen when the element is adde...
The bonding forces in ionic solids such as NaCl are very strong, yet many ionic solids dissolve readily in water. Explain why. The strength of an atom's attraction for the electrons in a chemical bond is the atom's what? Give a good d...
