Note: Pb reacts slowly with acids like HCl and HNO3 and releases bubbles of Hydrogen gas on reaction. Reaction 2: Pb (s) + 2 H2SO4→ PbSO4 + SO2 + H2O Lead Sulphuric acid lead Sulphate (II) Sulphur Dioxide Water Note: Lead does not react with sulphuric acid, that’s why the ...

3. Iron slowly reacts with cold hydrochloric acid and forms iron (II) chloride with the liberation of hydrogen gas. 4. Copper does not react with hydrochloric acid. This shows that copper is less reactive than hydrogen. When a metal reacts with dilute nitric acid, no hydrogen gas is produ...
Reason (R): Iron slowly reacts with oxygen and form iron oxide. Q.7. Assertion: Nitrogen is a non-metal. Reason: Nitrogen has 5 valence electrons. Q.8. Assertion: Al2O3, is an amphoteric oxide. Reason: Al2O3 reacts with acid as well as base to form salt and water. ...
Producing other metals with thermite reactions Hello all, I am curious as to whether it is possible to create aluminium from a thermite reaction. Thermite, as standard, uses aluminium and iron oxide, which react together when burnt to create a blob of molten iron. I would like to achieve a...
ANNEAL: The process of heating glass or metal to a specific temperature for a set period of time (depending upon the substance and the intended application), then slowly cooling it to toughen the substance and reduce the brittleness that develops while working it. Small pieces can be heated w...
Aside from these fascinating properties, the most interesting thing for us is the fact that it reacts — and not in a dangerous way — with oxygen to form a solid oxide on its surface. I think of it kind of like a water balloon or a water bed, in which this oxide layer not onl...
