Iron metal reacts with oxygen to produce iron(iii) oxide. if you have 12.0 moles of iron for complete reaction, you need(can someone explain and show work) .9.0 moles of o2 and produce 6.0 moles of fe2o3.2.9.0 moles of o2 and produce 3.0 moles of fe2o3.3.12.0 moles of o2 and produce 24.0 moles of fe2o3.4.5 moles of o2 and produce 3.0 moles of fe2o3.5.none of the above

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?

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.

Answer asap need by wednesday morning calculate the ph of 0.036m naoh best answer will be brainliest
