Answer» Answer: 1.A gaseous reducing AGENT which is basic in nature. ==> NH3 - Ammonia is basic in nature as it has a lone pair and also it can act as a reducing agent as nitrogen is the lowest oxidation state thus nitrogen can be oxidized thus reducing the other substance. Thus it acts as both a reducing agent as well as a base. 2. A METAL which cannot be used for the preparation of hydrogen using dilute acids. ==>Metals which LIE below hydrogen in the activity series i.e. CU, Ag, Au cannot displace hydrogen from dilute acids, because they are less reactive than hydrogen. 8. |
