Please be descriptive and use examples. Also provide reference of where you got the information so I may use in the future. The role of catalysts is critical in many chemical reactions. They have great consequence in the fields of medicine and pharmacology.
Identify the two important classes of catalysts.
Choose a catalyst that exists in the human body. Explain its importance and how it works.
Analyze the chemical reactions that take place when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.
in photosynthesis, plants use energy from the sun in combination with carbon dioxide and water to form glucose (C6H12O6) and oxygen. If 4.50 moles of water react with carbon dioxide, what mass of glucose is produced?
Oxygen gas reacts with powdered aluminum according to the following reaction: 4Al(s) + 3O2 (g) = 2Al2O3(s). How many liters of O2 gas, measured at 779 mm Hg and 30 C, are required to completely react with 2.5 mol of Al?
What mass of NaOH can this buffer neutralize before the pH rises above 4.00?
Calculate the number of moles of solute present in each of the following solutions.
Does the octet rule mean that a diatomic molecule has 16 valence electrons? Select from the following:
