Answer: Although it is possible to have more than one state, it is also possible to have only one state.
Explanation: Just took the test
Compressions are regions of high pressure due to particles being close together
rarefactions are regions of low pressure due to particles being spread further apart
Longitudinal waves are often demonstrated by pushing and pulling a stretched slinky spring
If solutions of nh4cl(aq) and nh3(aq) are mixed, the ions in the resulting solution that would be the spectator ions in any acid-base chemistry occurring in the solution would be the chloride ions. The mixture is a common buffer of ammonia and ammonium chloride. NH4Cl is a salt that is soluble in water dissociating into NH4+ and Cl-. The chloride ions are the spectator ions while NH4+ ions would be the conjugate acid for the buffer solution. Buffer solutions are solution which would resist change in pH when acid or a base is being added to the solution. The equilibrium reaction of the buffer solution in this problem would be
NH3 + H2O = OH– + NH4+

<span>1.Captive breeding: people can capture two organisms from the same species and wait for them to breed. 2.Laws and treaties: the government can make a law how many organisms to kill or not kill an organism in that area. 3.Habitat preservation: people can preserve a area for animals to live and breed. Hope this help :D</span>
