The pH of the buffer that consists of 0.55 M HNO₂ is 3.3, which is acidic.

<h3>What is the common name for 0.55 M HNO₂?</h3>

The common name for 0.55 M HNO₂ is Nitrous acid. Only in solution, the gas phase, and in the form of nitrite salts is nitrous acid, a weak and monoprotic acid, known to science. Amines are converted into diazonium salts using nitrous acid. To produce azo colors, azo coupling processes use the resultant diazonium salts as reagents. A nitrogen oxoacid is a nitrous acid. It is a nitrite's conjugate acid. To treat cyanide poisoning, sodium thiosulfate is combined intravenously with nitrous acid (as sodium nitrite).

Answer:

The answer to your question is:

a) 31.75 cm

b) 0.475 miles

c) 2.44 yards

d) 11496.04 inches

Explanation:

Convert

a)           12.5 in to cm

         1 in ------------------- 2.54 cm

       12.5 in ----------------    x

            x = 12.5(2.54)/1 = 31.75/ = 31.75 cm

b)          2513 ft to miles

           1 mile -------------- 5280 ft

           x miles ------------ 2513 ft

        x = 2513(1)/5280 = 0.475 miles

c) 2.23 m to yards

              1 m -------------   1,094 yards

            2.23 m ----------     x

       x= 2.23x1.094/1 = 2.44 yards

d)  292 m to inches

            1 m ---------------- 39.37 inches

          292 m -------------     x

    x = 292 x 39.37/1 = 11496.04 inches
