Answer:
The partial pressure of carbon dioxide is 22.8 mmHg
Explanation:
Dalton's Law is a gas law that relates the partial pressures of the gases in a mixture. This law says that the pressure of a gas mixture is equal to the sum of the partial pressures of all the gases present.
In this case:
Ptotal=Pnitrogen + Poxygen + Pcarbondioxide
You know that:
- Ptotal= 0.998 atm
- Pnitrogen= 0.770 atm
- Poxygen= 0.198 atm
- Pcarbondioxide= ?
Replacing:
0.998 atm=0.770 atm + 0.198 atm + Pcarbondioxide
Solving:
Pcarbondioxide= 0.998 atm - 0.770 atm - 0.198 atm
Pcarbondioxide= 0.03 atm
Now you apply the following rule of three: if 1 atm equals 760 mmHg, 0.03 atm how many mmHg equals?
Pcarbondioxide= 22.8 mmHg
<u><em>The partial pressure of carbon dioxide is 22.8 mmHg</em></u>
Answer:
hr
Explanation:
because it's short for hour
Answer:
The reaction is reactant-favored
Explanation:
If we take a look at the reaction equation, Zn2+ (aq) + Co (s) Zn (s) + Co2+ (aq) and consider the reduction potential of the species involved
Zn^2+(aq)/Zn(s)= -0.76
Co^2+(aq)/Co(s)= -0.28
It can easily be seen that the reduction potential of zinc is more negative than that of cobalt. Hence the electrochemical reaction is not spontaneous as written but will greatly favour the reverse reaction.
Hydrogen is the only element in entire periodic table with only 1 proton in its nucleus.
