PH, POH, and Concentration Formulas pH and pOH Formulas
Concentration Formulas
pH = -log[H30
[H30*) = 10-PH
pOH = -log[OH]
(OH) = 10-POH
pH + pOH = 14.00
[H30*JOH-] = 1.0 * 10-14

A solution has a pH of 4.20. Using the relationship between pH and pOH, what is the concentration of OH?
OA 9.9x10M
OB 6.2 * 10M
OC 6.3 * 105M
OD 6.7 * 10M
OE 1.6 * 100M

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?
