Answer:
0.0073 g
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.010 M
Volume = 25 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 25×10⁻³ L
Thus, moles of HCl :
Moles of HCl = 0.00025 moles
Considering the reaction shown below as:-
2 moles of HCl reacts with 1 mole of
So,
1 moles of HCl reacts with 1/2 mole of
Also,
0.00025 moles of HCl reacts with mole of
Mole of = 0.000125 moles
Molar mass of = 58.3197 g/mol
Mass = Moles*Molar mass = = 0.0073 g
Answer:
Balanced reaction:
Explanation:
- It is an example of double displacement reaction.
- Here anions and cation of two reagents interchange between themselves.
- 2 molecules of HCl (hydrochloric acid) reacts with 1 molecule of
(sodium sulphite) to produce 2 molecules of NaCl (sodium chloride) and 1 molecule of
(sulphurous acid)
- Balanced reaction:
