Answer : The final volume of will be 10.5 liters.
Explanation :
Formula used :
where,
w = work done = -865 J = -8.54 L.atm
Conversion used : (1 L.atm = 101.3 J)
= external pressure = 635 mmHg = 0.836 atm
Conversion used : (760 mmHg = 1 atm)
= initial volume of gas = 0.290 L
= final volume of gas = ?
Now put all the given values in the above formula, we get :
Therefore, the final volume of will be 10.5 liters.
NO, two atom with the same mass number can never be isotope of each other.
This is because for atoms to be considered as isotopes, they must have the same number of protons but different number of neutrons. There is no way two atoms will have the same mass number and their proton number will be the same, this means that two atoms with the same number of mass number can not be isotope of each other.
Answer:
Explanation:
We can use Gay-Lussac's Law of Combining Volumes to solve this problem.
Gases at the same temperature and pressure react in the same ratios as their coefficients in the balanced equation.
1. Write the chemical equation.
Ratio: 2 L 1 L
2H₂ + O₂ → 2H₂O
V/L: 1.2
2. Calculate the volume of O₂.
According to Gay-Lussac, 1 L of O₂ forms from 2 L of H₂.
Then, the conversion factor is (1 L O₂/2 L H₂).
Answer:
Net equation: Cu + 2Ag+ ⇒ 2Ag + Cu2+
Explanation:
Cu + 2N03- + 2Ag+ ⇒ 2Ag + 2NO3- + Cu2+
The 2NO3- cancel out since they're spectator ions
∴ Cu + 2Ag+ ⇒ 2Ag + Cu2+
Half equations are:
Cu ⇒ Cu2+
2Ag+ ⇒ 2Ag
Balancing both sides of each equation with electrons will lead back to the Net equation.
