Which statement correctly describes the relationship between thermal energy and particle movement?
Hunter-Best [27]

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.

Why is it that no two elements have the exact same emission spectrum?​
jonny [76]

Answer:

When atoms are excited they emit light of certain wavelengths which correspond to different colors. Each element produces a unique set of spectral lines. Since no two elements emit the same spectral lines, elements can be identified by their line spectrum.

A 50.0 −mL sample of 1.50×10−2 M Na2SO4(aq) is added to 50.0 mL of 1.28×10−2 M Ca(NO3)2(aq). What percentage of the Ca2+ remains
Norma-Jean [14]
When we have Ksp CaSO4 = 9.1x10^-6 so by substitution in Ksp formula:
Ksp CaSO4 = [Ca+2][SO4] 
1.9x10^-6   = [Ca+2][1.5x10^-2]
∴ [Ca+2] M in the solution =1.27x10^-4
when percent remaining = [Ca in solution]/[C original value] * 100
                                          = [(1.27x10^-4*(50ml+50ml)]/[1.28x10^-2*50ml]*100
                                          ≈ 2%
