Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution () and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.
This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.
As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution
Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
Answer:- B.
Explanations:- A precipitation reaction is a double displacement reaction in which a solid salt is formed.
If we look at all the given equations then it's only second reaction in which a solid salt (CdS) is formed. In rest of the reactions there is no solid salt formed.
It means A, C and D are not the right choices and so the correct choice is only B.
Here the phase are given for all the products. If the phases are not given then we use the solubility chart to see which reactions would form the precipitate.
Since, the precipitate is formed only in second equation, the correct choice is B.
