Indoor air. a convective kerosene heater is tested in a well-mixed 35 m3 atm, having an air exchange rate of 0.42 ach. the room is free of no before 9. (15 points 25 °c the and 1 atm, having an air e ng heater. after one hour of operation, the no concentration reached 5.2 ppmv a conservative pollutant, calculate the emission rat assuming that no no is e (mg/hr) of no from the heater.

Yes you are correct use the scientific method

Cause its being chemically applied?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
