Answer : The reaction requires 242 grams of HF.
Explanation : Given,
Mass of = 182 g
Molar mass of = 60 g/mole
Molar mass of HF = 20 g/mole
First we have to calculate the moles of
Now we have to calculate the moles of HF.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 1 mole of react with 4 moles of HF
So, 3.03 moles of react with moles of HF
Now we have to calculate the mass of HF.
Therefore, the reaction requires 242 grams of HF.

Answer:
Explanation:
Hello,
In this case, since the density is the ratio of the mass and volume:
For the given density and volume, the correct mass which fills the given volume is:
Best regards.
Explanation:
When the covalent bonds in a molecule are polarized so that one portion of the molecule experiences a positive charge and the other portion of the molecule experiences a negative charge. This separation of opposite charges creates an electric dipole.
Answer:
0.016 moles of product will obtain.
Explanation:
Given data:
Moles of K = 0.032 mol
Moles of product = ?
Solution:
Chemical equation:
4K + O₂ → 2K₂O
Now we will compare the moles of K with K₂O.
K : K₂O
4 : 2
0.032 : 2/4 ×0.032 = 0.016 mol
0.016 moles of product will obtain.
