When aluminum, AlAl, metal is dipped in an aqueous solution of hydrochloric acid, HClHCl, hydrogen gas, H2H2, is produced with t
kifflom [539]

Answer:

Balanced equation: 2Al(s)+6HCl(aq.)\rightarrow 2AlCl_{3}(aq.)+3H_{2}(g)

Explanation:

  • Al is an metallic species with a standard reduction potential of -1.66 V( E_{Al^{3+}\mid Al}^{0}=-1.66V).
  • H_{2} is present at the intermediate position in electrochemical series with a standard reduction potential of 0 V (E_{H^{+}\mid H_{2}}^{0}=0V).
  • So, when Al is dipped in aqueous solution of HCl, Al is readily oxidized to produce Al^{3+} whereas H^{+} is reduced to H_{2} .
  • Hence, as a whole, aqueous AlCl_{3} and gaseous H_{2} is produced as products.

Balanced equation: 2Al(s)+6HCl(aq.)\rightarrow 2AlCl_{3}(aq.)+3H_{2}(g)

How can chloroform dissolve in water? Include information about molecular shape and polarity.
suter [353]

Answer:

You can dissolve about 1g of chloroform in a 100g of water; slightly less if the water is hot. This would not generally be considered 'soluble', but it's not entirely negligible either, depending on your purposes. chloroform is insoluble in water since it does not have any hydrophillic groups.

hope this helps you uwu
