The Haber process is very important for agriculture because it converts N2 (g) from the atmosphere into bound nitrogen which can be taken up and used by plants. The reaction is N2 + H2->NH3 This reaction is exothermic, but is carried out at relatively high temperatures.
Determine number of moles of oxygen molecules are in the cylinder and compute the mass of solid C 2 H 3 NaO 2 required mixing with 60.0mL of .125M C 2 H 4 O 2 to form a ph 4.20 buffer?
which of the following shows the acids in order from strongest to weakest? The order of atomic radii is I > Br > Cl
