Answer:
Because they do not naturally react with other elements
Explanation:
Since noble gases do have a fulfilled valence shell, they do not react with other elements because they're already stable by the themselves.
Answer:
As K >>> 1, the reaction will shift to the products
Explanation:
To know the direction of any reaction you must calculate the equilibrium constant, K. If K is < 1, the reaction will shift to the reactants and if k > 1 the reaction will shift to the products.
With the reactions:
<em>HSO₄⁻ ⇄ SO₄²⁻ + H⁺ Ka = 1.26x10⁻²</em>
And:
NH₄⁺ ⇄ NH₃⁺ + H⁺ Ka = 5.6x10⁻¹⁰
The inverse reaction:
<em>NH₃⁺ + H⁺ ⇄ NH₄⁺ 1/Ka = 1.8x10⁹</em>
<em />
The sum of the reactions:
HSO₄⁻ + NH₃⁺ + H⁺ ⇄ NH₄⁺ + SO₄²⁻ + H⁺ K = 1.26x10⁻² ₓ 1.8x10⁹ = 2.3x10⁷
<h3>As K >>> 1, the reaction will shift to the products</h3>
By weight the hydroxides are 45.9% of the weight
Hi there,
I believe that your answer to this will be 234 g NaCL
this is because i made a reaction equation:
The reaction equation:
2Na + Cl₂ → 2NaCl
Molar ratio of Na to NaCl = 2 : 2 = 1
Moles of Na = 92/23
= 4
Moles of NaCl = 4
Mass NaCl = moles x Mr
= 234 grams
Hope this is correct :)
Have a great day
The volume of the gas when the container is cooled from a temperature of 300 K to 200 K is 0.83 L
<h3>Charles' law </h3>
Charles' law states as follow:
V₁ / T₁ = V₂ / T₂
Where
- V₁ is the initial volume
- T₁ is the initial temperature
- V₂ is the new volume
- T₂ is the new temperature
<h3>How to determine the new volume </h3>
From the question given above, the following data were obtained
- Initial volume (V₁) = 1.25 L
- Initial temperature (T₁) = 300 K
- New temperature (T₂) = 200 K
V₁ / T₁ = V₂ / T₂
1.25 / 300 = V₂ / 200
Cross multiply
300 × V₂ = 1.25 × 200
Divide both side by 300
V₂ = (1.25 × 200) / 300
V₂ = 0.83 L
