All the elements in group 18 are in a gaseous state (state true or false) ​
AleksAgata [21]

Answer:

The correct option is;

True

Explanation:

The noble gases are the group 18 elements, all of which are monoatomic gases, located in the extreme right of the periodic table. Due to their filled outermost or valence shells,and their nonreactive nature, the noble gases where initially known as inert gases.

The noble gases have very low melting points and boiling points as hey have very weak inter atomic forces between their atoms such that they all appear as gases under standard atmospheric temperature and pressure conditions.

A mass spectrometer is being used to monitor air pollutants. It is difficult, however, to separate molecules with nearly equal m
tatyana61 [14]

Answer:

4.2 m

Explanation:

The energy (E) of the selector region of the spectrometer is:

E = v*B (equation 1)

Where v is the velocity, and B the magnetic field.

The force with which particle forms a curved path can be calculated by:

\frac{mv^2}{r} = qB'

Where r is the radius of the particle, m is the mass, and q the electric charge. So:

r = \frac{mv}{qB'}

For equation 1: v = E/B, so:

r = \frac{mE}{qBB'}

The two species will be separated by Δr = 0.42 mm

Δr = Δm*E/(q*B*B')

E/(q*B*B') = r/m

Δr = Δm*r/m

r = m*Δr/Δm

r is the large of curvature, m is the avarege mass = (28.0106 + 28.0134)/2 = 28.012:

r = (28.012*0.42)/(28.0134 - 28.0106)

r = 11.76504/(0.0028)

r = 4201.8 mm

r = 4.2 m
