place when -
(a) dilute sulphuric acid reacts with zinc granules
(b) dilute hydrochloric acid reacts with magnesium ribbon
(c) dilute sulphuric acid reacts with aluminium powder
(d) dilute hydrochloric acid reacts with iron filings,​

Answer 1

Answer:

Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction as well as combination reaction.

2Mg(s)+O

2

(g)→2MgO(s)+energy

Answer 2

Answer:

a)H2SO4(aq) + Zn(s) gives ZnSo4(aq) + H2(g)

b)2HCl(aq) + Mg gives MgCl2 + H2

c)H2SO4(aq) + 2Al gives Al2SO4 + H2

d)2HCl + Fe gives FeCl2 + H2
