Nac2h3o2 is not a component of the hc2h3o2 equilibrium. explain hc2h3o2 equilibrium

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
