All of them are right except the neutron one. The neutrons is actually 176 because you subtract the number of protons from the atomic mass to find this.
Answer:
n= 0.08186
{He}2s^2 2p^6
Explanation:
PV=nRT
n=PV/RT
n= (1.220 atm)(4.3410 L) / (0.0821 atm*L/mol*K)(788.0 K)
n=0.08186
As for the electron configuration:
Ne:
{He} 2s^2 2p^6
or long hang:
1s^2 2s^2 2p^6
The statement of letter B, the collisions of particles with one another is completey elastic, is true about Kinetic Molecular Theory. Elastic collisions means that there is no energy transfer between the particles.
Explanation:
they are located in the neucleus
H2O is the correct answer :)
