SrBr2 + (NH4)2CO3 → SrCO3 + 2 NH4Br

If 2.1993 moles of (NH4)2CO3 are reacted, how many grams of SrCO3 will be produced?

324.6g

Explanation:

From this given problem, it is desirable to solve from the known specie to the unknown.

The balanced chemical combination is given as:

          SrBr₂   +     (NH₄)₂CO₃    →     SrCO₃   +    2NH₄Br

Given;

           2.1993 mole of (NH₄)₂CO₃  ;

Unknown:

           Mass of  SrCO₃ produced;

From the balanced equation, we see that;

                1 mole of  (NH₄)₂CO₃ reacted to produce 1 mole of   SrCO₃

                2.1993 mole of (NH₄)₂CO₃ will produce 2.1993 mole of SrCO₃

Mass of SrCO₃ produced = number of moles x molar mass of SrCO₃

Molar mass of SrCO₃ = 87.6 + 12 + 3(16) = 147.6g/mol

Mass of SrCO₃ = 2.1993 x 147.6 = 324.6g

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

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).
