Mass of copper produced from copper oxide</h3>
The mass of copper that will be produced from copper oxide is calculated as follows;
2Cu + O₂ -----> 2CuO
2 1 2
2(63.5) ------------ 2(79.5)
x ---------------------- 4 g
x = (4 x 2 x 63.5)/(2 x 79.5)
x = 3.19 g
Thus, the mass of copper that will be produced from copper oxide is determined as 3.19 g.

Answer:
AgCl
Explanation:
The reaction is AgNO3 (aq) + NH4Cl --------->AgCl(s) + NH4NO3.
Silver chloride is an insoluble salt that will precipitate out of the reaction mixture. It can then the filtered off, washed and dried.
<span>The NaCl suffers decoupling forming a cation Na+ and an anion Cl-, having free electrons the same becomes good conductor of electrical current.
NaCl ----------> Na+ + Cl-
A mixture of water and salt, we can separate the Same by means of simple distillation, this means separates through boiling temperature, the water being a substance with a lower boiling point this will vaporize, passing through the condenser where it receives a cooling, falling in béquer droplets of water and in the initial will remain empty container only the salt.
