Answer:
Theoretical yield is 10.0g of HF.
Explanation:
Theoretical yield is defined as the yield of a reaction assuming a 100%.
In the reaction:
SiF₄(s) + 2H₂O(l) → 4HF(aq) + SiO₂(s)
2 moles of water produce 4 moles of HF.
4.51g of H₂O are:
4.51g ₓ (1mol/18.02g) = 0.250moles of water. Moles of HF:
0.250moles H₂O ₓ (4mol HF/2mol H₂O) = 0.500mol HF
In grams:
0.500mol HF ₓ (20.01g / 1mol) = <em>10.0g of HF - theoretical yield-</em>

I hope it helps!
Hey there!
Just say what color you think the mixture would look like if those elements were combined. Personally I don't know because I don't have context, but if it comes to it just pick a color :)
Good luck, have a good night.
Answer:
0.111 mol
Explanation:
We can solve this problem by using<em> Avogadro's law</em>, which states that at constant pressure and temperature:
Where in this case:
We <u>input the data given by the problem</u>:
- 150.0 mL * n₂ = 50.0 mL * 0.332 mol
And <u>solve for n₂</u>:
Explanation:
The answer is to this question is
60 m/s.
