Ciprofloxacin and Levaquin (Levofloxacin) are in the same drug class (fluroquinolones). It makes sense that you would be allergic to both. You probably are allergic to other drugs in the same class such as moxifloxacinI, Ofloxacin, etc.s a fluoroquinolone, it is in the same class of agents as ciprofloxacin, enoxacin, levofloxacin, lomefloxacin, norfloxacin, and ofloxacin. Nalidixic acid is also a quinolone drug.
STC is calculated by taking the Transmission Loss (TL) values tested at 16 standard frequencies over the range of 125 Hz to 4000 Hz and plotted on a graph. Your curve (what you actually measured) is compared to standard STC reference curves (see appendix).
Step 2. Use the molar ratio from the balanced equation to convert moles of #CaC_2# to moles of #C_2H_2#. Step 3. Use the Ideal Gas Law to calculate the volume of #C_2H_2# at STP. STP is defined as a pressure of 100 kPa and a temperature of 273.15 K. The volume at STP is 882 mL.
