Answer:
The partial pressure of hydrogen gas at equilibrium is 1.26 atm
Explanation:
Let's use the molar fraction to solve this:
Molar fraction = Moles of gas / Total moles
Molar fraction = Gas pressure / Total pressure
Without equilibrium, we can think that the total system pressure is the sum of the partial pressures of each gas.
1 atm N₂ + 2 atm H₂ = 3 atm
Molar fraction for H₂ = 2 atm / 3atm → 0.66
Let's replace the molar fraction in equilibrium
Gas pressure / 1.9 atm = 0.66
Gas pressure = 1.26atm
Answer:
The answer is D)They have the same charge but different masses.
The number of neutrons in a nucleus affects the mass of the atom but not its chemical properties. Thus, a nucleus with six protons and six neutrons will have the ...

Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.
