Answer : The volume for 6.0m HCl solution required = 62.5 ml
Solution : Given,
Initial concentration of HCl solution = 6.0m
Final concentration of HCl solution = 1.5m
Final volume of HCl solution = 250 ml
Initial volume of HCl solution = ?
Formula used for dilution is,
where,
= initial concentration
= final concentration
= initial volume
= final volume
Now put all the given values in above formula, we get the initial volume of HCl solution.
= 62.5 ml
Therefore, the volume for 6.0m HCl solution required = 62.5 ml
Answer: 15.0 moles of 
are formed from 30.0 mol of 
Explanation:
The balanced chemical reaction is :
According to stoichiometry :
2 moles of give = 1 mole of
Thus 30.0 moles of will give =
of
Thus 15.0 moles of are formed from 30.0 mol of
<h2>Acetic Acid</h2>
Explanation:
- Initial alcohol that is formed from methane is methanol that can be converted to acetic acid.
- Methanol in presence of
and hydrogen gas gets oxidized to acetic acid with the release of water.
Hence, compound A will be Acetic acid.
→ 
- The acetic acid formed can be transformed into -
→ 
The product formed is methane and carbon monoxide.
2. → 
The product formed is formaldehyde and water.
3. 
→ 
The product formed is sodium acetate, carbon dioxide, and water.
the cut pieces will have their own north and south pole
