Answer:
3rd option: AX + BY ⇒ AY + BX
Explanation:
The 2nd option is a single displacement reaction where one bound atom is displaced.
Logically, it would follow that a double displacemnt would be one where two bound atoms, i.e. X and Y, are displaced.
A is the answer to the question you asked.
Answer: Amount of sodium chloride produced is 25.43 grams.
Explanation:
To calculate the moles:
Given: Mass of sodium = 10 g
Molar mass of sodium = 23g/mol
![\text{Moles of sodium}=\frac{10g}{23g/mol}=0.4347mol](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20sodium%7D%3D%5Cfrac%7B10g%7D%7B23g%2Fmol%7D%3D0.4347mol)
The balanced equation is:
![2Na+Cl_2\rightarrow 2NaCl](https://tex.z-dn.net/?f=2Na%2BCl_2%5Crightarrow%202NaCl)
By Stoichiometry of the reaction,
2 moles of sodium produces 2 moles of sodium chloride
So, 0.4347 moles of sodium will produce =
of sodium chloride.
Molar mass of sodium chloride = 58.5 g/mol
Putting values in equation 1, we get:
![0.4347mol=\frac{\text{Mass of NaCl}}{58.5g/mol}=25.43g](https://tex.z-dn.net/?f=0.4347mol%3D%5Cfrac%7B%5Ctext%7BMass%20of%20NaCl%7D%7D%7B58.5g%2Fmol%7D%3D25.43g)
Hence, amount of sodium chloride produced is 25.43 grams.
