1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl If 15 grams of copper(II) chloride react with 20 grams of sodium nitrate how much sodium chloride will be produced? g NaCl

13.45 grams of NaCl will be produced

Explanation:

Given:

Mass of CuCl2 = 15 grams

Molar mass of CuCl2 = 134.5 g/mol

Mass of Na(NO3) = 20grams

Molar mass of Na(NO3) = 85 g/mol

To find:

Amount of Sodium chloride produced = ?

Solution:

No of moles of CuCl2 = 15/134.5 = 0.11 moles

No of moles of Na(NO3) = 20/85 = 0.23 moles,

1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl

from the reaction, 1 mole of copper chloride reacts with 2 mole of NaNO3 to produce 2 moles of sodium chloride.

Hence, 0.11 mole of copper chloride will react with 0.23 mole of NaNO3 to produce 0.23 moles of sodium chloride.

Mass of 0.23 moles of NaCl = 0.23 × M.M of NaCl

(Molar mass of NaCl = 58.5)

Mass of 0.23 moles of NaCl = 0.23 × 58.5 = 13.45 grams

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

there all right good
