Increased growing crops season seems the most reasonable, since if we have many droughts, we can't farm nor have water to live. Rising sea levels aren't safe since it cloud flood an area of home. And increased heat waves speaks for itself, and not many people can deal with heat.

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)

Which instrument is most often used to measure acid volume before a titration begins?
Darya [45]

<span>Good Morning!
 
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.
