The answer you selected in the picture is correct!
Answer:
The reactants Cu(SO)₄ and Na₂(NO)₃ are reacting to produce Na₂(SO)₄ and Cu(NO)₃
Explanation:
When we describe a reaction by a chemical reaction, we put the reactants in on the side and the other side the products. A simple arrow (→) represents an irreversible reaction, the double arrow (⇄) represents a reversible reaction (the products are forming the reactants too).
So, for the reaction given, it's irreversible, and the reactants Cu(SO)₄ and Na₂(NO)₃ are reacting to produce Na₂(SO)₄ and Cu(NO)₃.
Answer: The concentration of excess in solution is 0.017 M.
Explanation:
1.
moles of
1 mole of give = 1 mole of
Thus 0.019 moles of give = 0.019 mole of
2. moles of
According to stoichiometry:
1 mole of gives = 2 moles of
Thus 0.012 moles of give = moles of
As 1 mole of neutralize 1 mole of
0.019 mole of will neutralize 0.019 mole of
Thus (0.024-0.019)= 0.005 moles of will be left.
Thus molarity of in solution is 0.017 M.
