Which teacher studied the subcellular organization of bacteria and discovered a protein?
Hartman
What is the molar mass of hydrogen?
1 g/mol
What is the ideal gas law?
PV=nRT
This theory states that in order for a collision to be effective, reactant particles must possess a sufficient amount of kinetic energy and particles need to be oriented correctly to break the necessary bonds of the reaction
What is collision theory!
