If a chemical reaction such as the formation of Iron oxide contains 4 atoms of iron (Fe) in the product, how many atoms of iron (Fe) would be in the
reactants? *

12 atoms of iron (Fe)
8 atoms of iron (Fe)
4 atoms of iron (Fe)
2 atoms of iron (Fe)

Which of the following statements is true? question 4 options: nuclear decay rates vary with the conditions of the reaction, but chemical reaction rates do not. chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not. neither chemical reaction rates nor nuclear decay rates vary with the conditions of the reaction. both chemical reaction rates and nuclear decay rates vary with the conditions of the reaction.

What is the relationship between particles in matter

If you used the method of initial rates to obtain the order for no2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 m, 0.100 m, & 0.050 m no2.
