An IV solution contains 135 mEq/L Na+, 45 mEq/L K+, and 12 mEq/L Ca2+. If HCO3- is the only anion in the solution what is its concentration in mEq/L?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

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
