Why is Antarctica an extreme environment? Why is the melting of ice not a chemical reaction? Why do polar bears depend on sea ice? Why are there larger waves in the Antarctic Ocean? Why is Arctic Sea ice important? Why is ice the solid form of water?
The ice in the saline solution will melt faster. Salt (NaCl) is an ionic compound, so when it dissolves into water, Na+ and Cl- ions will be in the solution. Since water is a polar chemical, the salt ions will make a weak bond with the water molecules - preventing them from bonding...
As an alternative, chemicals are often tested in laboratories. One isolated property, e.g., the corrosivity or ice melting ability, of the chemical is then chosen and tested. One of the most fundamental properties of a chemical is how much ice it can melt. The ice melting capacity is ...
The aluminum nanoparticles were obtained from Technanogy (Irvine, CA), and the physical properties of these nanoparticles are listed in Table 1. The sample with an average size of 12.5 nm radius has a broad size distribution with a standard deviation of 10.5 nm. The other four samples have ...
Ice:Ice is a solid form of the chemical compound water. It is a bit unusual because its density is lower than the density of cold liquid water which means it tends to float above liquid water bodies.Answer and Explanation: Melting ice decreases ocean salinity. This is because the melted ...
Why or why not? Give everyday examples of endothermic and exothermic processes. Endothermic Reaction: An endothermic process can be defined as a process in which the system absorbs energy from the surroundings. In a similar way, an endotherm...
Explain the chemical significance of the entropy change for dissolution of a salt. An ice cube tray is removed from the freezer section of a refrigerator. As it melts, the ice a. loses all entropy b. increases in entropy c. decreases in entropy d. constant entropy...
