Name two metals which will displace hydrogen from dilute acids and two metals which will not.
(a) What are metals? Name any five metals. (b) Name a metal which is so soft that it can be cut with a knife. (c) Name the metal which is the best conductor of heat and electricity. (d) What happens when a metal reacts with dilute hydrochloric acid? Explain with the help of an example. (e) Write the equation for the reaction of : (i) Magnesium with dilute hydrochloric acid (ii) Aluminium with dilutehydrochloric acid (iii) Zinc with dilute hydrochloric acid (iv) Iron with dilute hydrochloric acid Name the product formed in each case. Also indicate the physical states of all the substance involved.
Name two metals that can displace hydrogen from dilute acids to form metal salts and hydrogen gas.
• Metals that are placed above hydrogen in the reactivity series like potassium, sodium, zinc, etc. can displace hydrogen from dilute acids to form metal salts and hydrogen gas. • The reactivity series is the list of metals in the decreasing order of their reactivity. • The most reactive metal occupies the topmost position. • The least reactive metal is at the bottom. • When Sodium reacts with dilute hydrochloric acid it forms sodium chloride and hydrogen gas. • 2 Na ( s ) Sodium + 2 HCl ( dil ) Hydrochloric acid → 2 NaCl ( aq ) Sodium chloride + H 2 ( g ) Hydrogen gas • When Potassium reacts with dilute sulphuric acid it forms potassium sulfate and hydrogen gas. • 2 K ( s ) Potassium + H 2 SO 4 ( dil ) Sulphuric acid → K 2 SO 4 ( aq ) Potassium sulphate + H 2 ( g ) Hydrogen Hence, Sodium and Potassium are two metals that can displace hydrogen from dilute acids to form metal salts and hydrogen gas.

Okay in this problem we have to find out the two m which this place is illusion from dilute, is it? And the parameters which will learn this place there, hydrogen from radio deceits. Ah So from the activity series we can write the element is except this is photoshopped, so radiant sodium and we have a magnesium. Then we have an al monia. Then we have a zinc, I then I had an Andy hydrogen and below the hydrogen we have a copper and then we have mercury and then we have a silver. So from sodium to Iran all the elements can displace hydrogen from from…
