A column for gas chromatography features: length of packing 52 cm; volume flow rate 0.421 mL/min, volume of the analyte in the mobile phase (VM) 1.57 mL, and volume of the analyte in the stationary phase (VS) 0.321 mL. A chromatogram of a mixture of species A, B, C, and D provided the following data:

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?

Helium decays to form lithium. which equation correctly describes this decay?

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
