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:
Chemical Change
Explanation:
A chemical change is when something is turned into a new substances.
In this example the wood is being turned into ash.
To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
H = (30.0 g)(0.90 J/gC)(75 - 25)
H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
