Sodium (Na) and iodine gas (I2) react to form sodium iodine (NaI). Which equation is a correct representation of the balanced equation? 2Na+I2→2NaI

Na→NaI+I2

NaI→2Na+I2

I2→2NaI+2Na

2Na+I2→2NaI >> this is the correct answer I answered the test question and it was right.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
