,00 Plants. â Deer â Llon.Q3. Magnesium liberates Hydrogen gas when reacted with dil. HCI acid,Q4. a) Write one difference between Roasting and Calcination1000Jwhere as Copper cannot. Write chemical equation and give reason forthis chemical reaction.it why? |
Answer» <p>The position of zinc in the reactivity series is above hydrogen whereas that of copper is below hydrogen. It means that zinc oxidises (loses electrons) more easily than hydrogen whereas copper does not do so. </p><p>So, copper does not displace hydrogen from dilute acids.</p><p>Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g)</p><p>Like my answer if you find it useful!</p> | |
