The correct answer is C. Atoms are incredibly small and can bearly be seen with the most powerful electron microscopes. The nucleas of an atom contains protons and neutrons with electrons in orbitals around the nucleas. I hope this helps. Let me know if anything is unclear.
Answer:
Mass= 2.77g
Explanation:
Applying
P=2.09atm, V= 1.13L, R= 0.082, T= 291K, Mm of N2= 28
PV=nRT
NB
Moles(n) = m/M
PV=m/M×RT
m= PVM/RT
Substitute and Simplify
m= (2.09×1.13×28)/(0.082×291)
m= 2.77g
Answer:
6
Explanation
every p sublevel holds up to 6 electrons
so the 4p sublevel must hold up to 6 electonsr
As thermal energy increases and there is more particle movement.
- Thermal energy is the energy possessed by the system or object due to the movement of its particles.
- For example kinetic energy of the particles
- Higher the motion of the particles more will be the thermal energy of the system or object and vice-versa
- It is also termed as heat energy of a system or object
- The higher the thermal energy, the higher will be the temperature and vice versa.
So, from this, we can conclude that as thermal energy increases and there is more particle movement.
