Identify the two important classes of catalysts. Analyze the chemical reactions that take place when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.
In a particular titration experiment a 25.0 mL sample of an unknown monoprotic acid required 30.0 mL of .200 M NaOH for the end point to be reached. What is the concentration of the acid?
Derived from common sense is the same as the one derived mathematically from the equation obtained in the experiment.
Upon reaction with excess sulfamic acid, HSO3NH2, a 0.121g sample of a mixture of sodium nitrite, NaNO2, and sodium chloride, NaCl, produced 28.3 mL of nitrogen gas collected over water at 25.3 degrees Celsius and at a barometric pressure of 738 m..
