Carbon dioxide gas enters a pipe at 3 mpa and 500 k at a rate of 2 kg/s. co2 is cooled at constant pressure as it flows in the pipe, and the temperature of the co2 drops to 450 k at the exit. determine the volume flow rate and the density of carbon dioxide at the inlet and the volume flow rate at the exit of the pipe using (a) the ideal-gas equation and (b) the generalized compressibility chart. also, determine (c) the error involved in the first case.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
