Answer:
The reusable booster rockets of the space shuttle
When the overall charge is equal to zero
Charge = 1200 * 1.6 * 10^-19 = 1920 * 10^-19
Time = 3.5 µs = 3.5 * 10^-6 s
But Current = charge/time = (1920 * 10^-19) / (3.5 * 10^-6)
So Current becomes 548.5714 * 10^(-19-(-6))
So we have 548.5714 * 10^(-19 + 6) = 548.5714 * 10^(-13)
So we have 5.485714 * 10^(-15)
Chemical reaction: NaHCO₃ + HCl → NaCl + H₂CO₃.
H₂CO₃ → H₂O + CO₂.
If amount of sodium bicarbonate (NaHCO₃) is 1 mol, then from from reaction we can calculate amount of carbon dioxide:
n(NaHCO₃) . n(CO₂) = 1 : 1.
n(CO₂) = 1 mol.
At standard pressure and temperature:
V(CO₂) = n(CO₂) · Vm
V(CO₂) = 1 mol · 22,4 L/mol.
V(CO₂) = 22,4 L.
