1) By looking at the balanced equation, you can see that 1 mol of Al2S3 needs 6 moles of H2O to fully react . So to react 32 moles, you need 6x32moles of water.
moles H2O needed = 192 moles H2O
However, you don't have 192 moles, you only have 32- This means the water is the limiting
reagent.

So, to fully react 32 moles of water you only need 1/6 of </span><span>Al2S3
</span>
moles <span>of Al2S3
needed= 32* 1/6 =5,33 mol
2)
</span>For the <span>theoretical yield to be maximum amount of product possible we need the limiting reagent to
fully react.
So how many moles of H2S we obtain, from the 32 moles of H2O available to react?
6 moles H2O react to produce 3 moles H2S
moles H2S = 32 x (3 mol H2S / 6 mol H2O)
= 16 mol H2S
the theoretical yield of H2S = 16 mol </span>

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!
Answer:
D. Use x-ray radiation to see if there are any fractured bones.
Explanation:
The football player may have fractured a bone while he was practicing or playing, so it is best for the doctor to check if the player broke his bone or fractured it.
Answer:
It organizes all of the elements and it allows you to easily find the groups of elements such as
Group 1 of the periodic table consists of hydrogen and the alkali metals
Group 2 consists of the alkaline metals (batteries!)
Groups 3–12 contain transition metals
Groups 13–16 each contain at least one metalloid
Group 17 contains halogens
Group 18 consists of noble gases which are stable.
