Answer: Metals are shiny and lustrous with a high density. They have very high melting and boiling points because metallic bonding is very strong, so the atoms are reluctant to break apart into a liquid or gas.

Answer:
<em>Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go </em><em>out.</em><em> </em><em>S</em><em>ome </em><em>ways </em><em>of </em><em>using </em><em>fire </em><em>extinguisher </em><em>are:</em>
- <em> Water extinguishers work mainly by cooling (removing heat), but a dense spray of water droplets also helps to cut off oxygen. </em>
- <em> Dry powder extinguishers soak up heat, melt on the fuel, and cut off oxygen, but they also neutralize the </em><em>fuel</em><em> (cutting it off from the </em><em>fire)</em><em> </em><em>.</em>

<span>Yes that answer is correct. John dalton was an english scientist who lived during the 18th and 19th centuries and he is most famous for proposing the modern first widely recognized atomic theory. But, it is thought that his theory is influenced by the ideas of another scientist called Bryan Higgins .</span>
Answer:
The salt, LiNO₃ is a neutral, NR salt as it's a salt formed from the reaction of a strong acid and a strong base.In neutralisation reactions, acids and bases react to form salt and water.However, the salt formed may be acidic, basic or neutral. This is dependent on the type of acid and base which form the salt.A strong acid and a strong base react to yield a neutral salt like, LiNO₃.The equilibrium equation when LiNO₃ is dissolved in aqeous solution is;LiNO₃ + H2O ==>. LiOH + HNO₃
