Al2O3 issoluble in NaOH and HCl both. Does HCl react with sio2? Silicon oxide is an acid oxide. Therefore, it dissolves in alkaline solutions. Acid and acid oxidedo not react under normal conditions. How is Al2O3 reduced? Al2O3 is reducedby electrolysis at low potential and hi...
Explain why Zn dissolves in both HCl and HNO3 whereas Cu only dissolves in HNO3. Why is iron more reactive than copper? Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate (Cu(NO3)2). Why do copper (II) sulfate crystals not conduct el...
When a strong acid reacts with a weak base, the resulting solution will be ___. (a) acidic (b) basic (c) neutral. Classify the compound given as a strong acid, weak acid, strong base, or weak base. NH_3. Classify the compound given as a strong acid, weak acid, strong base, ...
The zinc borate reacts with the HCl present to give ZnCl which can cause crosslinking in PVC or polychloroprene resulting in added char. Flame retarding materials The mineral salts medium was prepared using distilled water as follows (g [L.sup.-1]): 1.2 K[H.sub.2]P[O.sub.4], 1.8 [...
contg. Cl, also include sufficient filler able to react with the noxious gases, (esp. HCl) given off during burning, to form neutral prodts. or those with little activity. The filler is chosen from Na2CO3, CaCO3, NgCO3, dolomite, or freshly-pptd oxides of Fe, Zn, Mg or Al. The ...

Would silver react with dilute hydrochloric acid? Why or why not? Why do metals tend to be malleable? Electroplating is performed by using a source of direct current. Why can't an alternating current be used? Can you explain why Manganese (IV) oxide is MnO_2 ...
A solution of indigo carmine that was known to be 6.00 times 10^{-6} M and had an absorbance of 0.735 at its maximum wavelength of 609 nm. Assume 0.0537 g of indigo was reacted with excess sulfuric acid and 10.25 L of a blue solution was obtained. If the...
Copper(II) sulfate solution with ammonia CuSO4+NH3 \longrightarrow H2SO4+HCuN Explain how adding more NH3(aq) caused the equilibria to shift again? Explain how blue food coloring can be distinguished from a solution of copper (II) nitrate. Would you be surprised i...
When a metal combines with non metal then a ionic compound is formed because metal and non metal forms ionic bond due to their properties. Oxides of metals are basic while non metallic oxide are acidic.Answer and Explanation: Metal oxide is formed when metal...
