7. If 100.0 grams of Hydrogen burns, how many moles of Water will form?
1 answer:
50moles of H₂O
Explanation:
Given parameters:
Mass of hydrogen burning = 100g
Unknown:
Number of moles of water formed = ?
Solution:
To solve this problem, we have to apply the mole's concept. We should first obtain the balanced equation for the reaction. Then express the mass as moles and compared to that of water.
Solve from the known to the unknown;
Equation:
2H₂ + O₂ → 2H₂O
Number of moles of Hydrogen gas =
Molar mass of H₂ = 2(1) = 2g/mol
Number of moles = = 50moles
From the equation of the reaction;
2 mole of H₂ produced 2 mole of H₂O;
Then 50 mole of H₂ will produce 50moles of H₂O
50 mole of water will be formed

Given :
Some compounds :
.
To Find :
Which of the following compounds has the most deshielded protons .
Solution :
Deshielded means nucleus whose chemical shift has been increased due to removal of electron density, magnetic induction, or other effects .
In simple words deshielding means the ability to shift protons .
Now , among Cl , I , Br and H . Cl is the most electron negative .
Therefore , deshielding will be more in .
Hence , this is the required solution .
