Explanation:
1)Mass of CO when 210.3 g of Fe produced.
Number of moles of 
in 210.3 g=
According to reaction, 2 moles of Fe are obtained from 3 moles of CO, then 3.76 moles of Fe will be obtained from : 
of CO that is 5.64 moles.
Mass of CO in 5.64 moles =
2)Mass of CO when 209.7 g of Fe produced.
Number of moles of in 209.7 g=
According to reaction, 2 moles of Fe are obtained from 3 moles of CO, then 3.75 moles of Fe will be obtained from : 
of CO that is 5.625 moles.
Mass of CO in 5.625 moles =
Answer:
All matter consists of indivisible particles called atoms. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Hope that helps : )

Answer:
see below
Explanation:
Swap cations and anions
K2NO3 is not balanced, it is either 2KNO3 or KNO3 and only 2KNO3 works in this case
FeCl2 (aq)+KNO3 (aq) → Fe(NO3)2 (aq) + 2KCL (aq)
