If im not mistaken about like three orr four
yea its four cuz its hard to exaplin lol
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
Explanation:
The balanced chemical reaction between copper (II) oxide and carbon monoxide is producing cooper and carbon dioxide:
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
where:
(s) - solid
(g) - gas
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.

The correct answer will be 15
Answer:
The answer to your question is: Molarity = 0.30
Explanation:
Data
V1 = 76 ml
C1 = 1.4 M
V2 = 208 ml
V3 = 104 ml
V water = 153 ml
Process
C1V1 = C2V2
C2 = C1V1/ V2
C2 = (1.4)(76) / 208
C2 = 0.51 M
Molarity = moles / volume
moles = Molarity x volume
moles = 0.51 x 0.208
moles = 0.11 Final volume = 0.208 + 0.153
Molarity = 0.11 / 0.361
Molarity = 0.30
