Answer:
Equilibrium will lie to the right.
Explanation:
That means HF is stronger acid than 
.
Alternatively, it can be said that 
is a stronger base than 
.
Therefore HF readily gives proton to to form and than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of and .
The correct answer is A. Glass does not have an orderly arrangement of the atoms, like the minerals. Glass lacks a crystal lattice structure, and is an amorphous solid. The atoms of glass are rigidly fixed but are arranged in an orderly fashion.
Hello!
To solve this question we are going to use the
Avogadro's Number, which tells us how many molecules of a given substance are in a mole. The Avogadro's number is
6,02*10²³ molecules/mol, and we are going to use this value in the following conversion factor:
So, there are 1
,69*10²⁴ molecules of SO₂ in 2,8 moles.
Have a nice day!

Using simply rational here:
1 Water= two hydrogen atoms+ 1 oxygen atom
The numbers provided would create seven water molecules based on having fourteen hydrogen’s (which would be seven times the two required for water) and seven oxygen.
So, 7
