Explanation / Answer
A) Reaction : aluminium + oxygen ----> aluminium oxide
balanced equation -: 4Al(s) + 3O2(l) -> 2Al2O3(s)
Aluminium will burn in oxygen with a brilliant white flame to form the trioxide alumnium(III) oxide, Al2O3.
B) Reaction : silver nitrate + pottasium chloride------> silver chloride + potassium nitrate
balaced equation -: AgNO3+KCl----->AgCl+KNO3(aq)
C) Reaction -: zinc + hydrochloric acid -------> zinc chloride+ hydrogen gas
balaced equation-: zn + 2HCl(aq) -> zncl2 + h2 (gas which forms bubbles)
D) Reaction -: sodium hydroxide+ hydrochloric acid ---> sodium chloride + water
balaced equation -: NaOH + HCl(aq) --------> H2O + NaCl(aq)
