1 Look at the following chemical equation. 4FeS + 702 → 2Fe2O3 + 4SO2 What is true about this chemical equation? A. It is balanced because the mass of the reactants is equal to the mass of the products. B. It is unbalanced because the mass of the reactants is greater than the mass of the products. C. It is balanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products. D. It is unbalanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products,

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).

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

the answer is 0.42 is that is an option. this question provides no info
