The answer to your equation is c
Answer:
It would change the charge of the atom.
Explanation:
Added electrons cause atoms to be negatively charged, lost electrons cause atoms to be positively charged.
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
