Answer : Option D) 
Explanation : When a positron is getting absorbed it means it will be
so, the
will get converted;
So, the whole reaction will be;
+
---->
.
This will convert the whole element of Cu will get changed into Zn. As, it absorbs by the positron, the atomic number gets increased from 29 to 30.
Answer: The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Explanation:
According to the dilution law,
where,
= molarity of stock
solution = 2.5 M
= volume of stock
solution = 5 ml
= molarity of diluted
solution = ?
= volume of diluted
solution = 750 ml
Putting in the values we get:
Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Answer:
magnesium
Explanation:
because zinc does not react with water because it too forms a protective layer of insoluble.
