The effusion rate is 1.125 cm/sec for ammonia.

How to find effusion rate ?

Effusion rate (r1) HCl = 43.2 cm/min

Molar mass (m2) NH3 =17.04g/mole

Molar mass (m1)  HCl    =36.46g/mole

  • Substitute the molar masses of the gases into Graham's law and solve for the ratio.
  • r1÷r2=√m2÷m1

       firstly convert 43.2 cm/min into cm/sec i.e., 0.72 cm/sec

      Then,

      0.72/r2 =√17.04/36.46

      r2= 1.125 cm/sec

Hence, the rate of diffusion of ammonia is 1.125 times faster than the rate of diffusion of hydrogen chloride.

Cesium metal is frequently used in photoelectric cells because the amount of energy necessary to eject electrons from a cesium s
dybincka [34]

Answer:

Wavelength of light in (nm) = 579 nm

Explanation:

At first you find out the amount of energy needed to just eject one electron. This is given by \frac{Energy}{Avogadro's number}

this energy is given in question in kj/mole. This \frac{Energy}{Avogadro's number} is the work function of cesium for each electron is equal to the planc'k  einstein equation.

List evidence that supports the Big Bang Theory.
Sphinxa [80]
The redshift<span> of distant </span>galaxies<span> means that the Universe is probably </span>expanding. If we then go back far enough in time, everything must have been squashed together into a tiny dot and the rapid eruption from this tiny dot was the Big Bang. Another piece of evidence could be that because light takes a long time to travel across the Universe, when we look at very distant galaxies or stars we are also looking back in time. This shows us that galaxies a long time ago were quite different from those today, showing that the Universe has changed. This fits better with the Big Bang theory than the Steady State theory
