How many grams of zinc must react with hydrochloric acid in order to produce 250 mL of hydrogen at 20.0 °C and 770 mm Hg

there is none because earth is stationary and flat.

the answer is minerals.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
