In which time period did alchemists attempt to change less valuable metals into gold? 8000 BC – 1000 BC 1000 BC – 450 BC 300 BC
SSSSS [86.1K]
Time Period 3 (300 BC to 1400 AD)

The alchemists were in pursuit of 2 ideals. First, alchemy came about from the belief that cheap metals can be transmuted to gold using the legendary substance <em>Philosopher's Stone</em> for the conversion. These views were greatly influenced by Aristotle. Thus, from 300 BC to 1400 AD, alchemists worked to make the conversion of cheap metals to gold a reality. However, it never succeeded. 

After this, the second ideal that the alchemists were in pursuit of was the concoction of an elixir of life to enable people to live longer and cure all ailments. This took place in the 1500s up to the end of the 1600s. Just like the pursuit of the first ideal, efforts to succeed in the second one all led to failure.

Which element has the highest electronegativity and why?
BigorU [14]

Answer:

See below

Explanation:

Hello there!

Electronegativity is the atom's tendency to attract electrons in a chemical bond

There are two trends to electronegativity:

  • Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example)
  • Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)

Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.

  • Sn belongs to group 4A (group 14)
  • Sb belongs to group 5A (group 15)
  • Te belongs to group 6A (group 16)
  • I belongs to group 7A  (group 17)

As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity

Hope this helps!

Which compound reacts with an acid to produce water and a salt
Hatshy [7]
I'm not exactly sure which one but I do know that an acid and a base react in a aqueous solution to form water, so i would probably eliminate the ones that aren't aqueous solutions.
