Answer:
2 Cu2O + C → 4 Cu + CO2
This is an oxidation-reduction (redox) reaction:
4 CuI + 4 e- → 4 Cu0 (reduction)
C0 - 4 e- → CIV (oxidation)
Cu2O is an oxidizing agent, C is a reducing agent.

The atomic theory changed because as time passed by our technolgy has been improving our ability to find answers to these theories.
Answer:
237.80mL
Explanation:
Molarity of a solution can be calculated using the formula;
Molarity = number of moles (n) ÷ volume (V)
However, we first need to calculate the number of moles of Cu(NO3)2 by using the formula:
moles = mass/molar mass
Molar mass of Cu(NO3)2 = 187.56 g/mol
moles = 146.59 ÷ 187.56
moles = 0.782moles
Molarity = n/V
3.28 = 0.78/V
V = 0.78/3.28
V = 0.2378L
In milliliters (mL), 0.24 litres = 0.24 × 1000
= 237.80mL
