Example: Sodium hydroxide gives sodium carbonate and water when it reacts with carbon dioxide. The formation of positive ions by metals is one chemical property that can be used to distinguish a metal from a non-metal. More reactive metals can displace less reactive metals from their salt solutions. So it should get corroded faster than Fe. This is an example of a single displacement reaction. sour taste and ability to dissolve some metals. (b) 31. (CBSE 2011) Answer: Hydrogen gas is formed. Name one metal and one non metal element which are obtained on a large scale from sea water. They cannot displace hydrogen from the non-metal anion.

State one chemical property which can be used to distinguish a metal from a non-metal. Answer: As nitric acid acts as a strong oxidising agent and oxidises the released H 2 gas to H 2 O and itself is reduced to either of these gases – N 2 O, NO 2 or NO. Non metals do not react with acid. Copper. H C l or H 2 S O 4 . Metals + Dilute acid → Metal salt + Hydrogen. Ions are formed because of loss or gain of electrons. Which metal is found in plants?

They cannot displace less reactive metals from their salt solution. Acid + metal oxide salt + water For example: 2 H C l + C u O C u C l 2 + H 2 O. Elements below hydrogen in the electrochemical series don't react with sulphuric acid. Metal oxides or $\ce{O2-}$ forms $\ce{OH-}$ after hydrolysis in the following reaction so metal oxides are basic in aqeous solutions. The reaction of a metal X with Fe 2O 3 is highly exothermic and is used to join railway tracks. 29. Answer: Answer. Since a chemical reaction between an acid and a metal will produce hydrogen gas, this can be used to determine whether a particular metal has reacted with an acid or not. 2Na + 2HCl → 2NaCl + H 2. ii) Magnesium.
