What is the standard heat of reaction for the formation of NO2(g) from NO(g) and O2(g)? Write the balanced equation first. You can find the standard heats of formation in table 17.4 of your book on page 580. (Show all work including the equation you use to solve). (5 points). See page 581 for an example.

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.

Reduction is a reaction which results in a in electrons and a in positive charge of the atom or ion 1) a- loss 1) b- gain 2) a-increase 2) b-decrease
