The question is incomplete, the complete question is;
Enter the chemical formula of a binary molecular compound of hydrogen and a Group 6A element that can reasonably be expected to be more acidic in aqueous solution than H2S , e.g. have a larger Ka.
Answer:
H2Se
Explanation:
The acidity and extent of acid dissociation (shown by Ka value) depends on the nature of the bond between hydrogen and the group 6A element.
If we compare the H-S bond and the H-Se bond, we will discover that the H-Se bond is longer, weaker and breaks more easily than the H-S bond. As a result of this, H2Se is more acidic than H2S.
Answer:
No because it's located inside the nucleus of the atom
hope this helps
have a good day :)
Explanation:
Answer:
Since 2H₂ + O₂ ---> 2H₂O
We need 2 moles of hydrogen for each mole of oxygen
So, we need 2(6) = 12 moles of H₂ but since we only have 10 moles,
H₂ is the limiting reagent
So since 2 moles of H₂ gives 2 moles of water,
10 moles of H₂ will give rise to 10 moles of Water with 1 mole of remaining oxygen
The Nazca plate is converging with the South American plate.
Explanation:
The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.
This mountain range typifies the geology and geography of the South American continent.
- Along this convergent margin, one plate subducts beneath the other.
- The oceanic plate due to its density goes into the mantle.
- The causes the continent riding to obduct and be forced.
- With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.
