Why does the reaction H2O + Cu→no reaction not proceed to a product?
2 answers:
Answer: Option (c) is the correct answer.
Explanation:
It is known that a stronger element is able to displace a less stronger element in a chemical reaction.
And, according to the reactivity chart hydrogen is more reactive in nature than copper.
Therefore, when Cu is added to then there will be no reaction because copper is less reactive than hydrogen.
Thus, we can conclude that the reaction not proceed to a product because copper has a lower activity than hydrogen and cannot replace it.

<u>Answer:</u> The molality of the solution is 0.1 m.
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute = 27.1 g
= Molar mass of solute = 27.1 g/mol
= Mass of solvent = 100 g
Putting values in above equation, we get:
Hence, the molality of the solution is 0.1 m.
