The molar mass of CO is 28 g/mol while that of CO2 is 44
g/mol. Let us calculate the total moles present in the container.
total moles = [5g / (28 g/mol)] + [5g / (44 g/mol)]
total moles = 0.2922 mol
Using PV = nRT, we get the pressure:
P = nRT / V
P = (0.2922 mol * 0.0821 L atm/mol K * 323.15 K) / 0.75 L
<span>P = 10.34 atm</span>
I am pretty sure it is the most reactive elements
Answer:
1350 g
Explanation: just add a 0
Answer is: Zn + Cu2+ → Zn2+ + Cu.
In this chemical reaction, there is transfer of electrons from zinc (Zn) to copper (Cu). Zinc change oxidation number from 0 to +2 (lost electrons) and copper change oxidation number from +2 to 0 (gain electrons).
Oxidation half reaction: Zn⁰ → Zn²⁺ + 2e⁻.
Reduction half reaction: Cu²⁺ + 2e⁻ → Cu⁰.
In other chemical reactions, there is no change of oxidation number of elements.
