By heating the water the temperature of 0C to 4C, one can observe a decrease in its volume. In this temperature range, there is the phenomenon of anomalous thermal expansion of water.
The volume of water in the range of 0C to 4C decreases and 4C to 100C from growing. This anomalous behavior of water is associated with the fact that liquid water <span>a temperature slightly above 0C, there are remnants of the loose structure of the ice. The temperature increase destroys this structure, allowing denser packing of the molecules, and thus the volume of water decreases.</span>
Answer:
The covalent bond in Cl₂ is break and combine with sodium to form NaCl through ionic bond.
Explanation:
Chemical equation:
Na + Cl₂ → NaCl
Balanced chemical equation:
2Na + Cl₂ → 2NaCl
The given reaction indicate the formation of sodium chloride.
Sodium chloride is an ionic compound. It is formed by the reaction of chlorine and sodium. The type of bond in Cl₂ is covalent. Both chlorine atoms are tightly held together through sharing of electrons. When sodium chloride is formed the covalent between the chlorine atoms are break and it react with sodium . The chlorine toms thus gain the one electron from the sodium atom and became negative ion while sodium by losing its one valance electrons became positive ions. The strong electrostatic forces are develop between them and ionic bond is formed.
