Consider the reaction 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s).
If 12.5 g of iron(III) oxide (rust) are produced from 8.74 g of iron, how much oxygen
gas is needed for this reaction?

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
