Witryna2 years ago. Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. WitrynaHydrogen will be produced because sodium is more reactive than hydrogen. Question Predict the product formed at the negative electrode during the electrolysis of …
Important Question for Class 10 Science Metals and Non-Metals ...
WitrynaZinc's relatively higher reactivity than copper is not because its highest occupied atomic orbital is $\ce{4s^2}$ while copper's is $\ce{4s^1}$; according to that magnesium should be more reactive than sodium as the highest occupied atomic orbital is $\ce{3s^2}$ while for sodium it is $\ce{3s^1}$. Therefore, this is not the case. Witryna11 lip 2024 · (ii) Zinc is more reactive than hydrogen. Therefore, it can displace hydrogen from dilute HCl whereas copper cannot, because it is less reactive than hydrogen. , (iii) It is because it is easier to reduce oxide ore as compared to sulphide ore.

Is copper more reactive than hydrogen? - Answers
WitrynaAnswer (1 of 7): Silver The standard electrode potential (reduction potential) of silver is more positive than that of all the other three metals. So, it would be displaced (reduced) from its salt solution by each one of them. WitrynaCorrect option is A) Copper does not react with dilute sulphuric acid, liberating hydrogen because copper is lower in electromotive series than hydrogen, or more fundamentally, because the magnitude of change in gibbs free energy when a single atom of elemental hydrogen ionizes is greater than the magnitude of the change in … Witryna31 mar 2024 · The metal which produces hydrogen gas on reaction with dilute hydrochloric acid as well as sodium hydroxide solution is _____ Answer. Answer: aluminium. ... Aluminium is more reactive than copper. Answer. Answer: True. Question 14. Non-metals react with water to form a gas which burns with a ‘pop’ sound. … shoe rally
