Most of the metals do not react with hydrogen, because the metals form compounds by losing electrons and hydrogen also form compounds by losing an electron. Thus, hydrogen does not accept electrons easily given by the metal to form a compound. But few metals like sodium, potassium, calcium an...
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 produced. This is due to the fact that nitric acid is a strong oxidising agent. As a result, as soon as hydrogen gas...
To prevent reaction with air, very reactive metals (K, Na) are stored underparaffin oil, and quite reactive metals (Ca) are kept inairtight containers. Gold is the least reactive of all metals - it does not react with oxygen and water, so it needs no special method of storage. A prote...
What happens when alkali metals react with molecular hydrogen? Alkali Metals: Alkali metals are elements of group 1.They are called alkali metals because the hydroxides they form on reaction with water, is highly alkaline in nature. The elements listed below constitute group 1 elements and are...
Magnesium, on the other hand, does not react with oxygen at room temperature. However, when magnesium is heated, it burns in the air, producing extreme heat and light, resulting in the formation of a basic oxide called magnesium oxide, which is a white powder: \(\begin{array}{l}2Mg(s...
How does the metal reactivity series work? Why is it not advisable to react an acid with sodium chloride directly? Why can't the halide ions be oxidizing agents? Why are ionic bonds not strong within cells? Why is fluorine a good choice to try to react with xenon? Why do some electroch...
Q.5. Assertion: Copper does not reacts with the H2SO4. Reason: Copper is more reactive than hydrogen. Q.6.Assertion (A): Rusting of iron is a slow combustion Reason (R): Iron slowly reacts with oxygen and form iron oxide.
For instance, phosphorus does not react with hydrochloric acid. 4. Electrolysis: - Metals: During electrolysis, metals are deposited at the anode. For example, during the electrolysis of copper sulfate solution, copper ions are reduced and deposited at the cathode. - Non-Metals: During ...
Metals are good conductor of heat and electricity; heaver, lead is an exception, as it does not carry electricity. Metals naturally react with various non-metals and forms compounds. Metals can react with bases and acids. E.g. 4 Na + O2→ 2 Na2O (sodium oxide), etc.Explore...
