In the important industrial process for producing ammonia (the haber process), the overall reaction is: . n2(g) + 3h2(g) → 2nh3(g) + 100.4 kj. a yield of nh3 of approximately 98% can be obtained at 200°c and 1,000 atmospheres of pressure. how many grams of n2 must react to form 1.7 grams of ammonia, nh3? a) 0.51 g. b)1.0 g. c) 1.4 g. d) 2.8 g

We are given with the equation that produces ammonia from the reaction of hydrogen gas and nitrogen gas. This is expressed in the balanced equation: N2+ 3H2 = 2NH3. We convert the given mass to moles of ammonia and multiply with the stoichiometric ratio of 1/2, further with the molar mass and the efficiency of the process.  The N2 needed is 1.372 grams or C. 1.4 grams

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

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).
