It’s b . The magnesium will dissolve and the copper will be deposited
Answer : The number of moles of formed are, 0.69 moles.
Explanation : Given,
Moles of = 0.345 mol
Now we have to calculate the moles of
The balanced chemical equation is:
From the balanced reaction, we conclude that
As, 1 mole of react to give 2 moles of
So, 0.345 mole of react to give mole of
Therefore, the number of moles of formed are, 0.69 moles.
For example phosphorus and oxygen can covalently bond to form a polyatomic ions, PO4³⁻ and PO3³⁻.
The answer is C) A length of one day
The point at which one drop of base turns the acid indicator into a pink color that lasts for thirty seconds in doing titration is called the end point or the equivalence point.
End point or the equivalence point is the one responsible for the pink color that lasts for thirty seconds.
