Why is helium preferred in weather balloons compared to hydrogen? Describe the method for producing hydrogen gas. How can you make a 1.5 M HCl solution? Give one property of hydrogen gas. What are two physical properties of nitrogen?
These rate differences are such that the addition of a small excess of enzyme will avoid any problems due to incomplete digestion. As always, however, one must be aware of the experimental molar concentration of recognition sites and digest conditions relative to that of the unit definition. See...
